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.
The reciprocal unit rate is 24/7 hour per room = <em>3-3/7 hours</em> per room.
ratio of voljumes = 3^3 : 4^3 or 27:64
small/large = 27 / 64
vol of smaller = 27 * 320 / 64
=135
