Question

4. Shoan takes 5 hours to complete 4 assignments. Find the

time taken to complete 3 assignments.

Answer 1

Answer: 3.75 or 3 3/4

Explanation:

This is a unit rate problem

A unit rate is a rate for one of something. (i.e, 1 pencil for 4 notebooks)

So first, to find the time needed for one assignment, we divided 5 hours by 4 hours.

5/4 = 1.25 (1 and 1/4)

Now we multiply the unit rate by 3.

1.25 times 3 = 3.75, or 3 3/4.

Answer 2

3.75 Hours or 225 Minutes

Explanation:

5/4 = 1.25 So it takes 1.25 hours to do an assignment

1.25 x 3 = 3.75

Which equals 225 Minutes
