Question

If it takes 5 people 5 minutes to make 5 pencils, how long would it take 100 people to make 100 pencils?

Answer 1

First let's figure out how many people it takes to make one pencil. One person can make 1 pencil in 1 minute. So, 100 people would take 100 minutes to get 100 pencils.

Or multiply all the 5's by 20 and you'll get 100 minutes.
