Question

Donovan took a math test and got 20 correct questions and 5 incorrect answers. What was the percentage of correct answers?

Answer 1

80%

Step-by-step explanation

Donovan got 20 questions correct and 5 questions incorrect.

This means that the total number of questions he attempted in the test is the sum of correct and incorrect questions:

Total = 20 + 5

Total = 25

To find the percentage of correct answers, we have to divide the number of correct answers by the total number of questions attempted and multiply by 100 (per cent).

That is:

`\begin{gathered} (20)/(25)\cdot\text{ 100 = }(4)/(5)\cdot\text{ 100} \\ =\text{ 80\%} \end{gathered}`

That is the percentage of correct answers.
