Question

The ratio of cars to trucks is 14 cars to 10 trucks.
If there are 5 trucks, how many cars are there?

Answer 1

c = cars

t = trucks

The ratio of cars to trucks is 14 cars to 10 trucks means:

c / t = 14 / 10

c / t = 2 ∙ 7 / 2 ∙ 5

c / t = 7 / 5

Replace t with 5

c / 5 = 7 / 5

Multiply both sides by 5

c = 7
