Answer: 80
Step-by-step explanation: To answer the question <em>135% of what number is 108</em>, 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 <em>of what number</em>, that's times <em>x</em>, <em>is 108</em>, equals 108.
So we have (1.35)(x) = 108.
Now to solve for <em>x</em>, since <em>x</em> 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 <em>x</em>.
On the right, 108 divided by 1.35 is 80.
This means that 135% of 80 is 108.
