Question

While completing a practice test online, M’Lea answered 6 out of 20 questions incorrectly. If the ratio of incorrect to total questions remains constant, how many questions should M’Lea answer correctly out of 30 questions?

Answer 1

M’lea should answer 21 answers correctly out of 30 questions, because the ratio is 3/10 if you multiply by 3 on 3/10 you get 9/30 which means she gets 9 answers wrong so you subtract the 9 to 30 and you get 21

The answer is 21
