Whenever you see "what number" use a variable. I like to use the variable "a".

First, change 5 percent to a decimal. Do this by taking the percent (5) and dividing it by 100. You will get 0.05.

Set your problem up. Whenever you see "is" in a math problem think of an = sign. Whenever you see "of" in a math problem think of multiplying so,

what number is 5 percent of 82,

a = 0.05 x 82,

a=4.1.
