Question

GRIDDED RESPONSE Mark got 18 out of 25

questions correct on his science test. What percent
of the questions did he get correct?​

Answer 1

72%

Explanation:

A percentage is a number out of 100. For example, 32/100 is 32%. What you want to do with percentages is multiply the denominator of a fraction so it becomes 100 and multiply that same number to the numerator. Sort of like a ratio!

If Mark got 18/25, we can multiply 25 by 4 to get 100 as the denominator.

Since you multiplied the denominator by 4, you have to multiply the numerator by 4 as well.

18 times 4= 72. So the numerator is 72 and the denominator is 100. The fraction is 72/100, which is 72% since it is out of 100.
