Answer:
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 <em>easiest</em> 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 <em>72</em>.
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.
Your answer is 8 your answer
