The sections on Mixtures and Work simply add one or two steps from your previous knowledge from Chapters 3 and 4. Answer the following questions to help you address your issues with these types of problems.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
1) I think mixture problems are not that complicated to set a chart because most problems tell you either one of the amount or percentage of an ingredient being mixed with water in certain mixture which are easy to plot onto a chart. Yes, you always need a 3rd row because mixture charts always have one more row for the mixture to be plotted after plotting the two components being mixed.
ReplyDelete2) Work problems are also not difficult to set up a chart because you just need to write in the rate, time, and work done which is similar to the things we have already learned before such as charting the rate, time, distance problems. Things you need to remember are first, the formula work rate x time = work done which is used in all work problems. Also, you need to know that almost all 'work done' in problems end up being 1 because it is the full amount of work done by the two or more people in the problem.
3) I personally think it is harder to use fractions in work problems because when adding or subtracting such fractions, we need to go to the long process of finding the LCD of the fractions, transferring each fraction so they all have the same denominator as their LCD to make it easier to add or subtract them. Unlike mixture problems where most deal with percentages, transferring decimals into percentages are much more simple because you just need to multiply 100 to it.
1) Yes, it's kind of difficult to set up in a chart. You only need percentage and amount of mixture but sometimes the informations they give you is little confusing. And you always need an extra 3rd row in your chart, because that row represents the mixture.
ReplyDelete2)No, it's easy to set up in a chart. Because this chart is only 2 rows and it always equals to 1. Also because the speed is always 1/something.
3)Mixture problems are more difficult to me to solve. Because it's more complicated to multiply and divide decimals than fractions. Also I think word problems are easier to set up the table and it's more simple.
1. I think that mixture problem is not that hard or complicated to set up a chart because if you know the categories and know what they mean, then it is easy because you just need to put numbers in the chart. Yes you would need a 3rd row for the extra "mixture".
ReplyDelete2. These problems are easy because it is always only two people and we always have to remember that the total equals 1.
3. I think that mixture problems are sometimes hard because the equation is sometimes complicated and you have to calculate a lot.
1. It think the mixture problem is difficult to set up in a chart because, when I try to set up, I am not sure where to put the numbers and how to label the chart. We always need an extra 3rd row in a mixture problem.
ReplyDelete2. No, work problems isn't difficult to set up than a chart because I know how the order should go and most of the problems are almost the same for setting up the problem.
3. Fractions are more difficult for me because I'm not used to using fractions and if their is a fraction, I always change it to a decimal.
1. The mixture problems are not that hard to make. It literally is just making words into numbers and boxes. Since Mixture problem is always adding or evaporating, it not very hard. There should be three columns since one is original fluid, the other is changing fluid and the last is the New product
ReplyDelete2. Work problems are not as hard as when we first learnt charting. The three row titles always remains the same so there is not many to be confused of. For these kind of problems, I have to remember the time should be in fraction and that I have to choose the time out of
3. I find the work problems a little bit more difficult since I learnt that I could just put the percentage of their actual number other than fraction Other than that, when I have to solve work problems, I have to find LCD and equalize the denominators which takes time
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDelete- the mixture charts aren't very hard because it's often pretty straight forward. The questions are pretty similar and they have the same format of the equation. Since it's a mixture everything is just added to the total end mixture which makes it more simple. I think there should be a third row for the new mixture just to make it less confusing. However, mixture problems are sometimes hard because it's sometimes easy to get mixed up with the time rate chart.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
- The word problems aren't the hardest things to do, but sometimes they get confusing depending on which types of chart you have to make for the specific problem. The wordings in the word problem can be difficult to show in the chart. The things to remember are to distinguish what happened from what and how that affects the other elements of the problem. Also, we have to remember to put the same unit and not to have decimal fractions.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
-I have to say that they are generally the same. However, the work chart is more confusing and hard to do because we always have to look carefully on what the question is asking and also because they are more complicated in the way of wording. Also, since the work problems are fractions, we have to simplify and make sure we distribute the number correctly. However, both aren't hard and relatively easy, but making charts without getting confused on chart format of the two is the most difficult part for me.
1) I think some mixture problems can be confusing to set up the chart because sometimes I get confused where to put the information given in the problem on the chart. Yes, we always need a 3rd row in your chart.
ReplyDelete2) Personally, I think it's quite easy to set up charts for work problems because I know pretty decently how to set up the chart and where specific information needs to go in the chart. For these types of problems, you always need to remember to write the work rate always as a fraction and when you are trying to figure out the equation, you have to add the amount of work done by the other amount of work done and equals 1.
3) In my opinion, work problems are a little bit easier than mixture problems. This is because I am more used to using fractions and I think finding the LCD doesn't take that much work to figure out. However, decimals are a bit more harder for me because decimals are a bit harder to calculate.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDelete- Mixture problems aren’t very difficult to set up as a chart because they are pretty straight forward. For example, if it involves a percent of a certain thing the charts are very easy to fill out because it always follows a specific way of how to fill out the charts for that problem. The other type of way to fill out mixture problems is always very easy. You just need to write the amount and the cost per each unit, then the final cost. You will always need the third row because well other than the two things that make up the mixture, this problem is a mixture problem! The third row is the most important row which is always going to be the mixture.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
- Work problems, in my opinion, are more difficult to set up as a chart because you always have to remember these key things when setting up the chart. Also the information is sometimes not very straight forward Although some people would think that these problems are easier, they are harder to me because I don’t really see the information in these problems as easily as I can see the information in mixture problems. For these problems, we always have to remember to make a fraction in the work rate column and make sure that we stay on one unit in one problem. We also have to remember to clear the fractions and always multiply the GCF on both sides of the equation.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
- I think work problems with fractions are harder to solve. This is because we can’t clear the fraction by multiplying it by anything. We always have the find the greatest common factor that all of the denominators would fit in to. However for decimals we just have to multiply the terms by the numbers 10, 100, 1000 etc depending on how far the decimal is to the left of the smallest number.
1). Mixture aren't very hard to set up in the chart but sometimes it's confusing to put numbers and sometimes there are hard words so it's kind of confusing. And yes, we always need 3rd law for the chart.
ReplyDelete2).To me, the work chart was pretty easy because all the total number would be 1. And we always have to remember to write the work rate as fraction. Finding LCD for the fractions weren't that hard and it was kind of fun after I understand the pattern.
3). For me the work problem was easier than the mixture problem. I am used to fraction and I don't think finding LCD isn't that hard. The decimal is harder to find the answer. The decimal is not that accurate compared to the work problem because the decimal can't be perfect natural number.
