Answer:
The two carpenters build in total per day 4/5 of a house
Step-by-step explanation:
we know that
One carpenter builds 1/5 of a house in 3/4 of a day
Other carpenter builds 2/5 of a house in 3/4 of a day
so
The two carpenters builds (1/5+2/5) of a house in 3/4 of a day
using proportion
Find out how many houses the two carpenters build in total per day
[tex]\frac{(3/5)}{(3/4)}\frac{house}{day}=\frac{x}{1}\frac{house}{day}\\\\x=\frac{4}{5}\ of\ a\ house[/tex]
