Peggy was taking a timed 60-question test. She was able to correctly answer 70% of the questions but had to skip the rest. How m

The answer should be 42.

Since there are 60 questions in the test and she managed to answer 70% of the questions correctly, that means that she answered 70% out of 60 questions correctly.

So you need to calculate how much 70% out of 60 is. Since % is always measured on a base from 0 (%) to 100(%), then 70% is equal to the fraction 70/100, simplified to 7/10. To know how much 7/10 out of 60 is,you just multiplie them and your answer will be 42.

I hope this helps you forward.
