Any percentage can be created into a fraction by taking the number in the percent (56.5) being put over 100, as percentages are out of 100:
56.5/100
This is not in simplest form, as it has a decimal, so try multiplying both the numerator and the denominator by 2:
56.5/100 x 2 = 113/200
Since our numerator, 113, is prime, this cannot be simplified, so this is the final answer.
Hope this helps!
