1.25 divided by 1.25 = 1
43.5 divided by 1.25 = 34.8
= 34 4/5
The unit rate for miles per gallon is 34.8 miles per gallon
Given:
Total distance Grace drove = 43 1/2 miles
Total quantity of gasoline = 1 1/4 gallons
Unit rate in miles per gallon = Total distance Grace drove ÷ Total quantity of gasoline
= 43 1/2 ÷ 1 1/4
= 87/2 ÷ 5/4
= 87/2 × 4/5
= (87 × 4) / (2 × 5)
= 348 / 10
= 34.8 miles per gallon
Therefore, unit rate for miles per gallon is 34.8 miles per gallon
