To determine a unit rate, the denominator of the fraction must equal 1.
Example:
17 miles
1 gallon
= 17 miles per 1 gallon = 17 miles per gallon
If the denominator of the fraction is not equal to 1, compute the unit rate by dividing.
Example:
120 hours
2.5 weeks
= 120 hours ÷ 2.5 weeks = 48 hours per week
Unit rates should fit the context of the problem and make sense.
Example: Five apples cost $1.75.
$0.35 per apple or approximately 2.86 apples per dollar.
