66&2/3 percent correctly answered, and therefore 33&1/3 percent wrongly answered.
-
7 is 33&1/3 percent of the amount of questions on the quiz.
-
7=%28%2833%261%2F3%29%2F100%29N, where N is the number of questions on the quiz.
N=7%28100%2F33%261%2F3%29
N=7%28100%2F%28100%2F3%29%29
N=7%2A3
highlight%28N=21%29
