Question

What is the unit rate for the ratio 4/7: 8/21?

Answer 1

The unit rate is 1.5

Explanation:

Given

`Ratio = 4/7 : 8/21`

Required

Determine the unit rate

To do this, we need to express the ratio as:

`Ratio = m : 1`

Where m is the unit rate

`Ratio = 4/7 : 8/21`

Express as fraction

`Ratio = (4/7 )/( 8/21)`

Solve

`Ratio = (4)/(7) * (21)/(8)`

`Ratio = 1.5`

Express as ratio

`Ratio = 1.5 : 1`

Hence, the unit rate is 1.5
