Question

NEED HELP NOW PLEASE!!!! D;

A student answered 72 problems on a test correctly and received a grade 83%. How many problems were on the test, if all the problems were worth the same number of points? (Round to the nearest whole number)

Answer 1

There were 86 problems on the test.

Explanation:

72/87 = y/100

You use cross multiplication to solve. When you do this, you get the answer 86.75 problems, but since you can't have .75 of a problem, the answer is 86.
