How many questions do i need to get right out of 70 questions to get an 80%?

Hello!

To find the amount of questions needed to be answer correctly to get an 80%, we need to first, convert 80% into a decimal, then, multiply the decimal by the total number of questions.

Remember that all percentages are out of 100, so, we divide 80 by 100, and that will give us the decimal.

80 / 100 = 8/10 = 0.80

With the decimal, we multiply the decimal by the number of questions.

70 × 0.80 = 56

Therefore, to get an 80%, you need to answer 56 questions correctly.
