Question

Ms. Wertz graded 20% of the tests for her class in 16 minutes. How many minutes will it take to grade all of the tests?

Answer 1

The entire class is done in 80 minutes

Explanation:

20 % = 20/100 = 1/5

1/5 of the class in 16 minutes

Multiply each by 5

1/5 *5 of the class in 16*5 minutes

1 of the class in 80 minutes

The entire class is done in 80 minutes
