Let x be the amount of paint needed for a whole room (in gallons).

¾x = 1½

Multiply both sides by 4 to get rid of denominators:

3x = 6

Divide both sides by 3:

x = 6/3

x = 2 gallons

6/4 gallons of paint was used to paint 3/4 of a room so 2/4 of pain is needed to paint 1/4 of a room so 1/2 gallon of paint is needed to paint 1/4 of a room so 2/4 x 4 = 8/4 = 2 gallons of paint are needed to paint the whole room
