Question

Lucy used 3 gal of paint to cover 900 ft. She needs to cover a total of 1,100 ft?.

How many more gallons of paint does she need? Show your work.

Answer 1

Explanation:

3 gal = 900 ft

... gal = 1100 ft

So, each gal is used for cover 300 ft,

Then,

`\sf (1100)/(900) * 3 = (11)/(3) = \boxed{ \bold{ \red{3 (2)/(3) \: gal}}}`

We need 3 2/3 gal to cover 1100 ft.

Hope it helps!
