Answer: 80
Step-by-step explanation: To answer the question 135% of what number is 108, we translate the question into an equation.
First we have 135% which we need to write as a decimal. Remember, to write a percent as a decimal, we move the decimal point two places to the left.
When we do that, we get the decimal 1.35.
Next we have of what number, that's times x, is 108, equals 108.
So we have (1.35)(x) = 108.
Now to solve for x, since x is being multiplied by 1.35,
we need to divide by 1.35 on both sides of the equation.
On the left, the 1.35's cancel and we have x.
On the right, 108 divided by 1.35 is 80.
This means that 135% of 80 is 108.
