Step-by-step 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

$Ratio = \frac{4/7 }{ 8/21}$

Solve

$Ratio = \frac{4}{7} * \frac{21}{8}$

$Ratio = 1.5$

Express as ratio

$Ratio = 1.5 : 1$

Hence, the unit rate is 1.5
