If I could wash 95 cars in 5 days, how many cars can I wash in 11 days?

Answer 1

"95 cars in 5 days" is a rate. It is

(95 cars) / (5 days)

(95/5) (cars/day)

19 cars per day. [please round this down to an integer number of cars]

Remember that (cars/day) * days = cars [days cancel]

( (95 cars) / ( 5 days) ) * ( 11 days)

(95/5) (cars/day) * (11 days)

(95/5) * 11 cars

19*11 cars

209 cars
