Question

a student answered 86 problems on a test correctly and received a grade of 98% how many problems were on the test?

Answer 1

86/x = 98%
86/x = .98
86 = .98x
86/.98 = x
87.76 = x

round up to 88

88 questions

Answer 2

I am not sure but my best guess is that there was 88 questions on the test. If you multiply .98 by 88 (.98*88) it should equal 86.24, which rounded is 86. I am not sure but that is my best guess, I do not know where that 88 came from though, it just popped in my mind. Hope it helps! :)
