Percentage question

Question

Of the 120 math tests given to students in the 8th grade, 54 earned a B. What percent of the 8th grade did not earn a B?

Answer 1

To find out the percentage that got a B you divide 54/120. That equals 0.45. To change a decimal to a percent multiply by 100. 0.45*100=45%. Then take 100-45=55%. So, 55% of the 8th graders did not get a B.
