# On a 50 question test, a student answered 5 questions incorrectly. What percent did the student answer correctly?

Feb 2, 2016

If $5$ questions were answered incorrectly, $45$ questions were answered correctly and the percentage answered correctly is 45/50 xx 100 = 90%

#### Explanation:

To find the percentage of questions answered correctly (50 of which $5$ were answered wrong so $45$ were answered right), we must divide the number of correct answers by the total number of questions.

In this case that would be $\frac{45}{50}$.

To convert that decimal fraction to a percentage, the answer is multiplied by $100$.

$\frac{45}{50} = 0.9$ and $0.9 \times 100$ equals 90%.
