Question

Together denise and her brother painted a total of 3/4 of her living room wall. denise painted 3/4 of that part, and her brother painted the rest. what part of the living room wall did denise paint herself?

Answer 1

If Denise painted 3/4 of what her and her brother painted, then she painted 3/4 of 3/4 of the room they both painted together:

3/4 of 3/4 is 3/4 times 3/4 = 9/16 of the room Denise painted herself.

Answer 2

9/16

Explanation:

If Denise ad her brother painted 3/4 of her living room and she painted 3/4 of that part, it means she painted

= (3/4) × (3/4)

= 9/16 part of the living room

Her brother would have painted

(3/4) - (9/16) = 3/16 part of the living room
