Can someone help me with some elementary math?

Write each set of numbers in order from greatest to least.

1) 1/2, 45%, 0.8

2) 1/25, 0.08, 5%

3) 5/4, 1.3, 40%

4) 7/8, 0.78, 87%

Can you tell me how you got to your answer. I NEED DETAILS. Thank you so very much!!!

You need to change each one to a fraction, a percent, or a decimal. So for the first one:

1/2 = .5, 45% = .45 and you have .8, so .8 is the largest.

1/25 = .04. you have .08. and 5% = .05, so .08 is largest.

Do the same with the other two and you will be able to work them out.

What you should do is convert those numbers into one form of a number. Either fractions, percents or decimals.

1) 1/2, 45%, 0.8

I think it would be easier to convert these into percents because 1/2 and 0.8 are easy conversion.

1/2 = 50%

0.8= 80%

45%

The order would be 0.8, 1/2, 45%

2) 1/25, 0.08, 5%

For this one I would convert to a decimal.

5% = .05

.08

1/25= .04

The order would be .08, 5%, 1/25

3) 5/4,1.3 ,40%

Here I would convert to a fraction.

5/4 = 1 + 1/4

1.3 = 1 + 3/10

40%= 40/100= 4/10

Then find a GCF between 4 and 10 so that the equations have equal denominators. The GCF is 20 so multiply the fractions with a denominator of 10 by 2 and the factions with a denominator of 4 by 5.

1 + 5/20 = 25/20

1 + 6/20 = 26/10

8/20

The order would be 1.3, 5/4, 40%

4) 7/8, .78, 87%

Here I would convert to a percent.

7/8 = .875 = 88%

.78 = 78%

87%

The order would be 7/8, 87% .78

Hope this is as detailed as you wanted. If not, I’m sorry. Hopefully somebody else will be more descriptive than I am.

Good luck!

you need to get everything down to its decimal equivilent. To do that with fractions take the top number and divide it by the bottom number. (1/25 = 1 divided by 25 which equals 0.04 ).

To find the decimal equivilent of a % divide the amount by 100 (5% = 5 divided by 100 which equals 0.05)

That makes figuring these out pretty simple.

The only tricky one is line 4 because 7/8 is decimally 0.875 which is techinally bigger than 87% which is only 0.87

The simplest way is to convert every number into %.

For instance, in # 1 one of the the numbers is 1/2 or 50/100, hence 50%. It’s easy to order that in referrence to the next number 45%. just keep going like that.

.8 which is 8/10ths right, 1/2 cause after all its only half, and 45% is last cause its less than half.

Should go 5%, then .08 and finally 1/25th.

5.4 cause its a whole number plus a quarter, 1.3 cause its a whole number plus extra, and finally 40% cause its less than a whole number.

Last one is tricky cause 87% and 7/8ths are the same arent they? and the 78 is 78% of a whole? Good luck and hope im not as stupid as i look

1/2 = .50

45%= .45

.8= .80

so it would be .8 then 45 then 1/2

1/2 is half of 1 which is .50

45% if you move over the decimal it is .45

.8 just put a 0 behind it and it means the smae thing. Now 80 is the biggest then 1/2 then 45%

1) 45%, 1/2, 0.8

2)1/25, 5%, 0.08

3)1.3, 5/4, 40%

4)7/8, 87%, 0.78

Chelsea did it incorrectly…her 3) and 4) are written from least to greatest.

turn all of the numbers to decimals.

1/2=.5

45%=.45

and .8

so its 45% 1/2 .8

well, lets do the first one together.

1/2 is one half. one half can also be said 50 %. So now, we know that the first one is 50%

okay so the second one is 45%. easy because you dont have to do anything.

the third one is .8 Wut u do for decimals is move the decimal place 2 to the right. so it would be 80 %. just like.6 would be 60%, and just like .79 would be 79 percent.

okay so now u have 50%, 45%, and 80%

therefore ur answers would be 0.8, 1/2, 45%

You have to correlate decimals (like 0.8), fractions (like 1/2) and percentages (like 87%) before you can answer the question.

For example: 1/2 = 50% = .50

so, #1 = 80%, 50%, 45% (assuming that 0.8 = 8/10), etc.
