If your percentage is 25% then just remove the % and write “25. ”
If you began with 25%, you should write “25/”
When converting a percentage to a fraction, the denominator is always 100, and the number you started with is always the numerator. [4] X Research source If you began with 25%, you should now have written “25/100. ”
For example in the case of 20/100, 20 has the following factors: 1, 2, 4, 5, 10, 20. 100 has the following factors: 1, 2, 4, 5, 10, 20, 25, 50, 100. The largest number that appears in both lists is 20, so 20 is the greatest common factor.
For example, let’s begin with 20/100. The greatest common factor is 20. 20 divided by 20 equals 1 and 100 divided by 20 equals 5. When written out in fraction form, our simplified answer is 1/5. [8] X Research source
Take, for example, 60% and convert this to 60/100. You might think that the largest common factor for these numbers is 10, which will leave you with 6/10. However, 6 and 10 share a common factor of 2, which means it can actually be reduced even further, to 3/5. If you end up with a decimal point in your fraction, then you’ve chosen a common factor that is too large for one of your numbers. Work backwards to find a smaller number that goes in an exact number of times for both the numerator and the denominator.
For example, take 32%, or 32/100. If you divide 32 and 100 each by 2, you get 16/50. If you divide the top and bottom by 2 again, you get 8/25. You can no longer divide these numbers by a common factor, so 8/25 is the simplest form of your fraction.
