Q5. is given in the attachment
Q.6
First figure out how much of the job each could complete in one day
The homeowner would take 7 days so in one day he would complete 1/7 of the job
The roofer would take 2 days so in one day he would complete 1/2 of the job
Together they would complete 1/7 + 1/2 = 2/14 + 7/14 = 9/14 of the job in a day
Now we need to figure out how many days (D) it would take to complete the job (J)
if 9/14 of the job was done per day. Think of the whole job as a percentage.. we want J = 100%
which as a decimal is J=1
The logic is (9/14 day)(#days) = 100 % or (9/14)D = 1 (9/14)D = 1
D = 14/9
So together they would take 14/9 days or 15/9 days to complete the job
This makes sense because alone the roofer would take 2 days. With the homeowners help it should take less than 2 days.
