# 25% of what number is 16?

Remember in mathematics “of” means “multiplied by” or “times.”

So, 25% of what number is 16 can be written as 25% * X = 16

25% * X is the same as 1/4 * X or X/4

Once you write that as X/4 = 16 you can solve to get X = 64

# What percent of 50 is 18?

Divide 18 by 50, then multiply by 100.

18/50 = .36 * 100 = 36%
