Percent means "divide by 100", "of" in Math means to "multiply", and "is" means "equal." Lets write what we know into an equation to make this easier.

36 = ?% x 80

We know that something x something equals a number, but we also know that the number divided by one something gives us the other something. Follow? If something % x 80 = 36, then 36 divided by 80 gives us the percent to fill in the question mark (when we multiply by 100). 36 divided by 80 = .45, or 45%

Check your work by finding 45% of 80. 80 x .45 = 36, so our answer is correct.
