Roberto paints 1/6 of a room in 1 hour.
Julio paints1/8 of a room in 1 hour.
Working together, they paint (1/6 + 1/8) = (4/24 + 3/24) = 7/24 room per hour.

Answer:
28/3
Step-by-step explanation:
2 1/3 divided by 1/4
We’ll start by 2 1/3
Multiply 3 x 2 and then add 1
3 x 2 = 6 + 1 = 7
Then add the denominator back
7/3
Now divide 7/3 by 1/4 like this!
Start by multiplying 4 by 7
4 x 7 = 28
Then multiply 3 by 1
3 x 1 = 3
Final results: 28/3
