Question

A factory builds 960 cars in 5 days. What is the average number of cars the factory produces per day?

Answer 1

`960/5=192`

Answer 2

192 cars/day

Explanation:

Using ratio:

`("car count")/("day count") ->960/5 ->(960-:5)/(5-:5)=("192 cars")/("1 day") -> color(blue)(192)color(white)(.)color(green)( ("cars")/("1 day"))`

`color(blue)(192)color(white)(.)color(green)( ("cars")/("1 day"))->color(blue)(192)color(white)(.)color(green)("cars/day")`

Do you spot the connection between ratio and the wording:

"count per day"
