Answer:

(2/7) cans/wall

Explanation:

We are asked for the cans of paint per wall, or cans/wall.

Cans = 2/3

Walls = 2 1/3 or (7/3) [Convert 2 to 6/3 by multiply by 3/3: 3*(3/3) = (6/3)]

Cans/Wall = (2/3 cans)/(7/3 walls) The unit becomes cans/wall, the desired unit.

Cans/Wall = (2/3)*(3/7) cans/wall

Cans/Wall = (6/21) cans/wall

Cans/Wall = (6/21) can be written (3*2)/(3*7)

The 3's cancel, leaving (2/7) cans/wall

CHECK:

Will 2 1/3 walls require (2/3) can of paint?

(2 1/3 walls)*((2/7) cans/wall))

(7/3 walls)*((2/7) cans/wall)

(7/3)*(2/7) cans

(7*2)/(7*3) cans

(2/3) cans YES
