What are some methods for changing fractions to a percent?

Answer 1

Well if you have a calculator, simplify the fraction to a decimal. Basically just type it in and hit enter. Then multiply be 100. That's your percent. If no calculator, multiply both the top and bottom of the fraction by the same number; one that will make the bottom equal 100. You can find this number by dividing 100 by the denominator (number on bottom). For example: 3/4 is 75%. To find this, divide 100 by 4 (the denominator), then multiply the answer (25) by the numerator (top number: 3) 25•3=75. The formula for this would be x/y=((100/y)•x)%
