Question

Sophia can wash 99 cars in 9 days.How many cars can Sophia wash per day?

Answer 1

Answer: Hi!

Here we're trying to find something called a unit rate. To find the unit rate in this situation, we have to divide the amount of cars by the amount of days:

99 ÷ 9 = 11

Sophia can wash 11 cars in one day.

Hope this helps!

Answer 2

`\Huge \boxed{\mathrm{11}}`

Explanation:

She can wash 99 cars in 9 days.

Divide number of cars by number of days.

99 cars / 9 days ⇒ 11 cars/day ⇒ 11 cars per day.
