you divide the numerator(top number) by the denominator(bottom number). for example ( PS this is a question from my hw.) OK um 33/40. into your calculator put in 33 and then press the divide button and put 40 . your answer should be .825 and then put a percent sign after if u have a fraction like this 4 3/5 then u make the whole number into a decimal like this 4. and then divide 3/5 which u will get 0.6 now put the 4. as the whole number and after it put 4.6%.
By definition, per cent means "hundredths", so it is very easy to convert decimal fraction
to per cents-- just move the decimal point two places to the right and add the per cent
sign.
Examples: 0.25 = 25%
125.1 = 1.251 %
.045 = 4.5 %
3 = 300%
To convert a common fraction to a per cent, convert it to a decimal by using division --
divide the numerator by the divisor and carry it out to decimal places, then do move the
decimal place as I said about to get the percent -
or if the numbers are small, just convert the denominator to 100.
Example 1/4 = 25/100 = 25%
2/7 =
.2 8 5 7 1/7
__________
divide 7 into 2 7) 2.0
1 4
6 0
5 6
4 0
3 5
5 0
4 9
so 2/7 = 28.57 1/7 % , close to 28.57%

You divide the numerator by the denominator, then multiply the result by 100. For example, if your fraction is 3/4, you divide 3 by 4, this gives you 0.75; then you multiply the result by 100, this gives you 75 (75%). (You can also first multiply 3 x 100, then divide this result by 4.)

for example:
33%
go 33/100
25%
go 25/100 = 1/4
for 57%
go 57/100
just start with 100 and reduce from there.
To change a percent into a fraction, divide the percent number by 100, and if you can, simplfy the fraction.
89.7% = 89.7/100 = 897/1000
45 percent in a fraction is 9/20.
Percent means "in one hundred". so x% as a fraction is x/100 .
17.5 as a percent as a decimal fraction is 16/3
