a painter is painting the ceiling of a square room. The walls are all 15 ft long. If a gallon of paint covers 45 square feet, how many gallons of paint will be needed to cover the entire ceiling?

15 * 15 = 225 square feet

225 / 45 = ?

15*15/45 = 5

Who makes up these questions or what kind of strange paint is this?

To paint a ceiling of that size should take about 1/2 gallon
( I know, I have too much time on my hand)

how did you get 5

The room is 15x15 feet, making 225 sq ft.

Each gallon covers 45 sq ft

5*45 = 225, so it will take 5 gallons.
Or, as we solved it, 225/45 = 5

What do YOU get when you divide 225 by 45?

225/45 = ?

you get 5

i know that but i did not understand
but now i do

thank you guys

You're welcome.

thanks Cierra and my name Is Tierra

you will get 5

That's correct! 225 divided by 45 gives you 5, so you will need 5 gallons of paint to cover the entire ceiling.
