Sarah's English test had 90 questions, and she got 18 questions wrong. What percent of the questions did she get correct?

So,
Sarah got 72/90 questions correct.
Simplify 72/90 72 = 2 * 2 * 2 * 3 * 3 90 = 2 * 3 * 3 * 5
Cross out "ones" 2 * 2 over 5
4/5 = 80%
Sarah got 80% of the questions correct

90-18=72 questions (answered correct) 72/90=0.8 To get the percent, you have to move the decimal point over two places, so 80%
