Question

mike can paint one house in two days. Ike can paint one house in three days, How many houses can they paint in 6 days if they work together

Answer 1

A: 1 every 2 days
B: 1 every 3 days
I know 5 days equals 2 houses. It would be around... 2.5 painted of a house.

Answer 2

mike = 1/2
ike = 1/3
6 days
therefore the no of houses =
mike*6 + ike*6
=1/2*6 +1/3*6
=3 + 2
=5 houses if they work together
