Question

Brendan got 31 questions correct on his social studies test and missed 9 questions. What percent did he have correct? Express as tenths.

Answer 1

Total number of questions/ Number correct gives you 31/40 = .775 but expressed as a percent it will move two decimal places and become 77.5%

Answer 2

The answer is 77.5%

Explanation:

Total questions Brendan solved are =
`31+9=40`

Number of correct question he got = 31

Number of missed questions by him = 9

We have to find the correct answer percentage, so we will divide the correct answer by total questions multiplied by 100.

`(31)/(10)*100` = 77.5%

Hence, the correct percent is 77.5 %.
