Question

99 is 180% of what number?

Answer 1

To translate this word problem into a mathematical problem we must look at the wording and realize that the word 'is' means equal, and the word 'of' means multiply.

Therefore the question can be translated into the equation

99 = 180% (n)

Next we convert the percent to a decimal by dividing by 100 or by moving the decimal two places to the left making 180% equal to 1.80.

99 = 1.80 (n)

next we divide by 1.80 on each side to isolate the variable.

`99/1.80 = n`

`n = 55`
