Question

Out of 30 problems on a test, Jose got 4 wrong What percentage did Jose get correct?

Answer 1

Jose got `86.7%` of the problems correct.

Explanation:

Percentage means "per 100" or "out of 100" so we can write this problem as:

`(30 - 4)/30 = x/100`: Using `(30 - 4)` because the question is about the percentage correct and to get the percentage correct you need to know the number correct not the number wrong (`4`).

`26/30 = x/100`

`(100*26)/30 = x`

`2600/30 = x`

`x = 86.7`
