Question

a student answered 86 problems on a test correctly and received a grade 98% how many problems were on the test if all the problems were worth the same number of points

Answer 1

98% Grade was achieved, so 0.98 of the questions were answered correctly.

n = number of problems


`(86)/(n) = 0.98 \\ \\ n = (86)/(0.98) \\ \\ n = 87.755...`

Our final answer can't be a decimal, so we round it to:


`n = 87`
