Question

On his third math quiz of the semester, Cooper answered 28 questions correctly and got 7 wrong. What is the ratio of the number of questions he got right on the quiz to the total number of questions?

Answer 1

Explanation:

Given that Cooper answered 28 questions correctly and 7 incorrect answers, If the total number of questions is x,

• let total number of questions be X,

therefore X = 28+7

= 35

• ratio of right answered questions to the total questions, R is

R =

`(28)/(35)`

=

`(4)/(5)`

therefore, the ratio is 4:5
