The word percent means per 100. So for example, 17% = 17/100. What if the percentage has a decimal in it? It still works the same way. For example, 17.5% = 17.5/100. We can multiply top and bottom by 10 to get 175/1000.

Divide the percentage by 100. For example 16% is 16/100 = 8/50=4/25.

I'll explain it in detail simply:
% means per 100, so 15% as a fraction is 15/100. To simplify the fraction you need to find the highest number that goes into both 15 and 100; that's 5. Then you see how many times 5 goes into 15 and 100. 3 times into 15 and 20 times into 100. Answer 3/20. So 3/20 is the same as 15%. To check: 1 twentieth of 100 is 5, so 3 twentieths are 15.

All percents are over 100 so 6% is 6/100 and 56% is 56/100. However you will want to reduce it to the lowest possible fraction. 50% or 50/100 is not in lowest terms. You must find a number that both the numerator (top number) and denominator (bottom number) are divisible by. In the case of 50/100 it is 50. Meaning 50/50=1 and 100/50=2 So reduced its 1/2. So:
50% = 50/100 =1/2
Lets try another one. 66% = 66/100. The can both be divided by 2, So it would be 33/50.
Quite simple really.

By definition, percentages are parts per 100, therefore make a fraction with the percent over 100, then simplify.
20% = 20/100 = 1/5

here is an example= .25= 25/100 = 1/4 or 20% of 100, 20/100 divide it be an equal number which is 20 and you get 1/5 or 35% of 70 =35/70 = 1/2 always divide the upper number into the bottom.

multiply fraction by a hundred over one....i.e. 3/4 times 100/1 equals 300/4 which is 75%...this applies to all fractions that you want to turn into percentages

Just place the percentage over 100. for example, 53% = 53/100
If simplifying can be done, then do it, it is advisable.
For Example: 25% = 25/100 = 1/4
Hope that Helped! =)

there is not really a formular what you really need to know is how to divide the number by 100,its all about moving the numbers into being a decimalif you are to change 0.07 to a fraction it would be 7/100

Changing Percentage to fractilon
Divide the percent by 100. remove the Percent (%) sign.
Example
30 %
30 / 100
- - - - - - -s-
