Question

Amy and Roger both wash windows at a large downtown building. Amy can wash 25 windows In 4 hours, Roger can wash 32 windows in 6 hours. How many windows can they wash together in 12 hours? [Type your answer as a number.)​

Answer 1

139 windows

Explanation:

you multiply the 25 by 3 because Amy washes 25 windows per 4 hours and 3x4 is 12 so that would be 75 then you multiply the 32 by 2 because 6x2 is 12 so that would be 64 then you add the 64 and 75 which would give you 139 windows for both of them in 12 hours
