First, we set each person to a variable.
If Peter=x, or (6/6)x
Ned=2 1/3 x, or (7/3)x, or (14/6)x,
Morris= (7/6)x
Since the total number of apples was 999, (6/6)x+(14/6)x+(7/6)x=999
Adding the x coefficients together, we get (27/6)x=999.
To get rid of the fraction, multiply both sides by (6/27).
This results in x=999*(6/27)
999*(6/27)=222
If we plug this in for each person, we get
Peter=222,
Ned=518,
Morris=259
It is also helpful to make a graph (as shown below) for convenience:
name | # of apples | value of apples | total # of apples |
Ned | |||
Morris | |||
Peter |
(obviously the 3rd column would not be needed for this problem)
