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

Explanation:

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

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

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

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