Question

In the last math test andrew answered 80% of all the questions correctly.If he answered 32 questions correctly, what was the total number of questions in the math test?

Answer 1

The total number of questions are 40

Explanation:

let the total number of questions be "x".

percent of questions answered correctly are 80.

In fractions 80% is
`(4)/(5)`

The total number of correctly answered questions are 32.

the equation is,

`((4)/(5))(x) = 32`

thus , x =
`((5)(32))/(4)`

x= 40
