Answer 2

Formula = Number x 100

Percent = 18 x 100

25 = 72

Following shows the steps on how to derive this formula

Step 1: If 25% of a number is 18, then what is 100% of that number? Setup the equation.

18

25% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

25Y = 18 x 100

25Y = 1800

Y = 1800

100 = 72
