Formula & How Fraction to Percentage Converter Works
To turn a fraction into a percentage, divide the numerator by the denominator and multiply by 100. 3/8 = 0.375, which is 37.5%. 7/20 = 0.35 = 35%, and 1/3 = 0.3333, which is 33.3%. To go the other way, write the percentage over 100 and simplify, so 45% is 45/100 = 9/20. A decimal is the percentage divided by 100. Use the conversion to compare scores, test marks, proportions of a budget or discounts that are given in different forms. Round at the end rather than part-way through so the answer stays accurate, particularly for repeating decimals such as thirds and sixths.
