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

1 Answer

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%#.
