Question

A student missed 3 problems on a chemistry test and received a grade of 92%. if all the problems were of equal value, how many problems were on the test? round off your answer to the nearest integer

Answer 1

So basically we know that three problems were 8% of the test, or one problem is 2.67 of the test. Now just divide 100 by 2.67 to get how many questions are in the test. It's around 37 questions.
