Question

lena has painted 3/4 of a room she has used 1 1/2 gallons of paint how much paint will she need for the whole room?​

Answer 1

That first answer was not helpful, so I’ll help. For 3/4 of her room, she used 1 and 1/2 gallons. If you divide that by 3, you get 1/2 gallon for each 1/4 of the room. So 1/2*4 equals 2 gallons total used.
