Word Problem multiplying fractions with fractions

by Moises Villalpando

Your job is to sweep 3/4 of the school's cafeteria. Your friend agrees to help you and sweeps 1/3 of your part. What fraction of the entire floor your friend agreed to sweep? What fraction of the the entire cafeteria floor you will have to sweep?

A quick multiplication of 1/3 and 3/4 = 3/12 = 1/4

So, your friend will complete 1/4 of the job
So, your part now is 3/4 - 1/4 = 2/4 = 1/2
You will sweep only half the cafeteria

Alternatively, you could write
3/4 = 1/4 + 1/4 + 1/4

and argue that you have 3 jobs to do consisted of 1/4, 1/4, and 1/4

If your friend takes 1 out of these 3 jobs, it means 1/4.
