The fuel efficiency of a truck in miles per gallon is 6.25 miles/gallon.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
65 miles ⇔ 10 2/5 gallons of fuel
65 miles ⇔ 52/5 gallons of fuel
By cross multiplication
65 × 5/52 miles ⇔ 1 gallon of fuel
1 gallon of fuel ⇔ 6.25 miles
Hence "The fuel efficiency of a truck in miles per gallon is 6.25 miles/gallon".
