Question 1205910
<br>
The other tutor shows one common method for answering the questions by finding the total number of man-days it takes to build the garage.<br>
A different way for solving problems like this is to look at how each change in the numbers affects the other numbers.<br>
We are given that it takes 3 people 4 days to build the garage.  Using that information....<br>
A) How long does it take one person to build the garage?
1/3 as many workers means 3 times as many days.  ANSWER: 4*3 = 12<br>
B) How long does it take four people to build the garage?
4/3 as many workers means 3/4 as many days.  ANSWER: (3/4)*4 = 3<br>
C) How many people are needed to build the garage in 2 days?
Half as many days means twice as many workers.  ANSWER: 3*2 = 6<br>
