a student answered 86% of the questions on a test correctly. he received a grade of 98%. how many questions were on the test?

Respuesta :

Let the number of questions on the test equal X which would be 100%

They answered 86 which equaled 98

Set up a ratio:

X/86 = 100/98

Cross multiply:

98X = 8600

Divide both sides by 98:

X = 87.75

Round to 87 questions
