Question

The printer can print 168 papers in 21 minutes. Enter the number of paper the printer can print in 10 minutes.

Answer 1

80 pages

Explanation:

We can use ratios to solve

168 papers x papers

------------------ = -----------------

21 minutes 10 minutes

168*10 = x * 21

1680 = 21x

Divide each side by 21

1680/21 = 21x/21

80 = x
