## Got any tips on finding percentages of a number?

Having a tough time remembering how to find the percentage of a number? Try turning the question word-for-word into an equation.

For *what*, substitute the letter *x*; for *is*, substitute an equal sign; for *of*, substitute a multiplication sign. Change percents to decimals or fractions, whichever you find easier. Then solve the equation.

**Example:** 18 is what percent of 90?

18 = *x*(90)

18/90 = *x*

1/5 = *x*

20% = *x*

**Example:** What is 15% of 60?

*x* = .15(60) = 9

or

*x* = 15/100 x 60 = 900/100 = 9
