tetrachloroethylene formula

Percentage Calculator

3 How to find X if P percent of it is Y Use the percentage formula Y/P% = X Example: 25 is 20% of what number? Convert the problem to an equation using the percentage formula: Y/P% = X Y is 25 P% is 20 so the equation is 25/20% = X Convert the percentage to a decimal by dividing by 100 Converting 20% to a decimal: 20/100 = 0 20
