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

1 Answer

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 45/50.

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

45/50 = 0.9 and 0.9 xx 100 equals 90%.
