John picks 12 lb of peaches. He divides the peaches between himself, his grandmother, and his neighbor in a ratio of 1:1:2, respectively. How many pounds of peaches does each person get?

himself: grandmother: neighbor: total

3                       3                   6           12

Step-by-step explanation:

himself: grandmother: neighbor: total

1                  1                     2             4

The total lbs is 12

12/4 = 3

Multiply each by 3

himself: grandmother: neighbor: total

1*3                  1*3                 2*3        4*3

3                       3                   6           12
