Question

Say that on your last science test, you scored 45 out of 75 points. What is your grade as a percentage?

Answer 1

60%

Explanation:

Find the fraction of the score `=> 45/75 = 3/5`
Multiply that with 100 to get the percentage `=> 3/5*100 = 60%`

Note : Percentage is just the way of telling what part of 100 is a fraction. For example,
the fraction `1/2` is equal to 50 parts out of 100.
Similarly, `1/5` is the same as 20 parts out of 100

So the score `45/75` which is the same as `3/5` is 60 parts out of 100, hence 60%
