So it took him 4/5 of an hour to paint 1/3 that means there is still 2/3 to go so that means that he will have two times that time to paint the rest of the room <u>4/5</u> = <u> ? </u> 1/3 2/3
using cross multiplication
(4/5)(2/3) = (1/3) (?) 8/15 = 1/3 ? divide both sides by 1/3 so that will be 8/5 that means it will take 8/5 of an hour to complete the rest or 12/5 total to do entire room
