The total number of questions is 25
Eric answered a total of 20 questions correctly
Firstly, we need a relationship between percentage, whole , and part
Part= whole x percentage
In the question, we are given
Part =20
Whole or total =25
20= 25 x percentage
Divide both sides by 25
20/25= percentage x 25/25
percentage =20/25 x 100%
percentage = 0.8 x 100%
Percentage =80%
The answer is 80 %
