To receive a grade of A on an 80-question test, 90% of the questions must be answered correctly. What is the maximum number of questions that can be missed to still receive an A?

The answer would be 8.

Step-by-step explanation:

This is a percentage question, and I have struggled with these before but this is the easiest way to solve it given these certain criteria.

Alright, so it's given that:

A) 90%= an A grade

and

B) This is an 80-question test.

Given these, we can do the following:

90% times 80, which equals 72.

Just to check, we know that to convert percentages to fractions, we move the decimal two spots to the left, therefore 90%= 0.90, or 0.9. We take 72 and divide it by 80, and we get 0.9, thus showing that it is correct.

Then, we do 80-72 and using simple math we get 8.
