<span>Example: 56.25%/100 = .5625, Next, count the number of digits to the right of the decimal point, say that number is n, and multiply and divide the decimal by 10^n. For your example n = 4 so multiply and divide the decimal by 10^4, which is 10000, giving 5625/10000 which is the fraction sought. This last operation converts the decimal fraction to a whole number needed for the numerator of the fraction. </span>
