To find a percentage out of a fraction we first need to find the fraction as a decimal, then a to a percentage.
1) First of of you divide the top number (numerator) by the bottom number(denominator).
For example, when doing 1/4, you divide 1 by 4 and you will find you will get 0.25.
2) To change a decimal into a percentage you simply multiply it by 100 and you will come up with 25%
Examples:
*1/5
=0.2
=20%
*1/10
=0.1
=10%
*3/8
=0.325
=32.5%

Get a calculator. Divide the top numerator (top number) by the denominator (bottom number) of the fraction. Starting after the decimal is your percentage.
For example 1/8 is one divided by eight: 0.125
Answer: 12.5%

3/5=60%; divide numerator (3) by denominator (5) to reach percentage.
4/10=40%, etc.

divide 100 by the denominator? (the bottom number) and times it by the number on the top.
example: 5/20 (100 divided by 20=5) (5X5=25) therefore 5/20 is 25%

Divide , then move the decimal place (which is always at the end of the number) 2 places to the right, then theres your percent
10/10 = 1.00 = 100%

it's easy just listen-
okay if you know how to "convert" fractions you;re good
so say you have 3/5 you have to multiply to get the bottom number to 100
so 5x20=100 now you multiply 3x20=60
so the fractions would now be 60/100 and the percentage would be 60%
get
if i helped please choose me as best answer!!!
