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%
