4 & 12/25 = 4 + (12/25) = 4.48
7/25 = 0.28

x = number of bags to start with
1 full bag weighs 0.28 pounds
x of them weigh 0.28x pounds
Set this equal to the total weight of all the rice (4.48 pounds) so we can determine x.
0.28x = 4.48
x = 4.48/0.28
x = 16
There are 16 bags to start with.

Cam uses 1/8 of them so she uses (1/8)*16 = 2 bags and is left with 16-2 = 14 bags.

Alternatively, because she uses 1/8 of the bags, she has 7/8 of the bags remaining.
(7/8)*16 = 14


Answer: Choice D

pounds of rice: 4 12/25 = 100/25 + 12/25 = 112/25

pounds of rice in each bag: 7/25

Number of bags: (112/25)/(7/25) = 112/7 = 16

Number of bags used: (1/8)(16) = 2

Number of bags left: 16-2 = 14

As a Math problem, the formulation is far from to be perfect and smooth.

Personally to me, this formulation makes me shudder.

Here is much better formulation.


        Cam distributes 4 12/25 pounds of rice in small bags evenly so that each bag weighs 7/25 of a pound.
        She uses 1/8 of the bags of rice. How many bags of rice are left?
