Answer 1

Idk what it has to do with simplifying but what I would do is multiply 1 times 3. That gives u 3. Then add Ben's one hour and Brooke's 3 hours together. That gives u 4 hours total.

Answer 2

Time Spent by Ben while cleaning his room=1 hour

⇒ Time Spent by Ben's Sister while cleaning his room=3×1 hour=3 hour--------------[As, it is given that, Ben's sister spent 3 times as many hours that ben spent while cleaning her room].
