divide the fraction into 100
1/4 = 25%
4 divided into 100 = 25
1/10 = 10%
10 divided into 100 = 10

Dividing the numerator (the top number of the fraction) by the denominator (the bottom number of the fraction) is the quickest and easiest way. If you want to convert 1/4 into a fraction it will come up as .25, which is 25% (multiplying it by 100). Anything above 1.0 in decimal form is more than 100% and anything below .10 (10%) needs a zero in front of it because it has only one digit. For example, 9% would be .09 in decimal form.

Right, What you need to do, is divide 100 (%and full amout possible) by the bottom of the fraction(denominator). Say you have got the fraction - 15/20, we can simply work out that it is 75% but what you must do is 100 divided by 20 = 5 then multiply the answer by the top part of the fraction. 15 x 5 = 75%

Multiply by 100:-
1/2 = 50%
3/4 = 75%
3/5 = 60%
are some examples.

if you express the fraction as hundredths, how many hunderedths there are is the percentage
4/5 =4 x 20 / 5 x 20......(you say 5 into 100 goes 20 times)
4x20/100
=80/100
=80%
3/4
4 into 100 goes 25 times so put 3 x 25 in the numerator (top line) and 4 x 25 in denominator (bottom line) to get 100 in the denominator.
3 x 25 / 100
= 75/100
=75%

To turn fraction into percentage, simply multiply the fraction with "100",

Just divide the top number by the bottom number - Then multiply the answer by 100
Or - Multiply the top number by 100 and divide that by the bottom number.
(does the same thing but use whichever way you can remember easiest)
Simple answer without harping on about numerators and denominators and jargon like that

Hi,
Divide the numerator by the denominator and multiply the result by 100.
Example:
Convert 3/4 to percent:
..._.75___
4|3.00
...28
......20
......20
........0
.75 * 100 = 75 %

Convert to a decimal (eg 1/4 = 0.25) and multiply by 100 (0.25 x 100 = 25. ans 25%)

a percentage is literally per hundred...
25% 1/4
33% 1/3
50% 1/2
75% 3/4
and you can extrapolate the missing numbers half of 25 is 12.5% 1/8th 6.25 is 1/16th 3.125 is 32nd
its all quite simple really
