Question

A group of workers can plant 3/4 acres in 4/5 days.

What is the unit rate in acres per day?

Write your answer in simplest form.

Answer 1

You can create two equivalent rates/ratios that can be used to find the number of acres for one day:

3/4 acres = x acres

4/5 day 1 day

You can use cross products to find the value of x:

4 x = 3 * 1

5 4

Divide both sides of the equation by 4/5 using multiplication by its reciprocal:

x = 3 * 5

4 4

x= 15 acre

16

So the unit rate per day is 15/16 acre in one day.
