For the fraction to turn into a decimal you take the numerator and divide by the denominator and you have decimal then you take the decimal and multiply it by 100 and then you have a percentage. Dan Yang =)
with the first fraction/percent change it to a second percent then you have to find how much it's away from the whole once you do that you get the final percent. So who ever has the highest final percent will be who has the largest percent of their money left. Danyang
Like Dan Yang said "to turn into a decimal you take the numerator and divide by the denominator and you have decimal then you take the decimal and multiply it by 100 and then you have a percentage.", so it means that to find the largest % we just take the % of money used and subtract it from 100%. Eric
In my opinion the first thing you should do, is think of there money as a whole of 100. Then change the fractions and decimals into percentages(which is easy if you are working with a whole of 100.). Just like Dan Yang said we should remember the connections between fractions, decimals, and percentages. Therefor you can easily compare the amounts that each girl spent.
For this question we would have to relate our prior knowledge back to Unit 9 in our - Math Text Book. In addition this question is trying to tell us to turn fractions & decimals into a percent. 0.75 = 75%. Quincy
Like Julie said, the 1st thing to do is to think as the money as a whole of 100. If you do that it makes it more correct & easier to turn the numbers into % because you think of it as 100's not 200, 300, or 400's. Quincy
At first changing fractions that have a denominator that is not 100 was difficult to me. But now I know that an easy way of doing that is multiplying the denominator by something to get to 100 and multiplying the numerator by the same number(if it is a number like 76 , that cant go into 100, then this strategy wont work). After I do that i can easily get the percentage to figure out the rest of the question.
Hey Eric that's right but we have to find what's left. To find it you have to find the other half. You can find the other half by which number reaches the whole so you use that number. Dan Yang
In my opinion I think that your strategies are very good but I got a new strategy. First you need to change every thing to a percentage “the denominator needs to be 100”. To change another number to 100 or another number you would need to multiply or do division. When your done take the nominator and multiply or divide it by the number that brought your denominator to 100. Order the number from less to greatest.
Ithink this is about turning fractions into decimals than percents. Dan Yang

ReplyDeleteMaybe we should order from least to greatest so the one at the front is the answer. DanYang
ReplyDeletewe should find a whole number as the money that they start with. Dan Yang
ReplyDeleteI think we should figure out witch lesson that fractions, decimals and percents are in.
ReplyDeletewith the first fraction/percent change it to a second percent then you have to find how much it's away from the whole once you do that you get the final percent. So who ever has the highest final percent will be who has the largest percent of their money left. Danyang
ReplyDeleteWe have to turn every thing into percentages. wyatt

ReplyDeleteProcess of finding percent of a decimal and/or fraction:
ReplyDeleteFraction-First divide the numerator by the denominator, Second take the decimal and multiply by 100
Decimal-Multiply decimal by 100

Adding to Julie's comment, an easier number that cam multiply easily into 100 is 25, 20, 10, 50, & 2. Quincy
ReplyDeleteFor the 4 over five I think you should change the denominator into 20 like the other one by mulitling by 4. Dan Yang
ReplyDeleteIf i have calculated correctly Josie spent 80% of her money, Christina spent 75%, Audrey spent 68% while Manny spent 85%. Eric

ReplyDeleteThis question is basically turning all decimals and fractions into percents and than subtracting them from 100. Eric
