Question 1208323
<pre>
Cam put 4 12/25 pounds of rice in bags that each weigh  7/25  pound. She uses 
1/8 of the bags of rice. How many bags of rice are left?
A)2 
B)4
C)8 
D)14

Total amount of rice (in pounds): {{{matrix(1,7, 4&12/25, "=", (25(4) + 12)/25, "=", (100 + 12)/25, "=", 112/25)}}}
Each bag contains {{{(7/25)lb}}} of rice, so total number of bags = {{{matrix(1,9, (112/25)/(7/25), "=", (112/25)(25/7), "=", (112/cross(25))(cross(25)/7), "=", 112/7, "=", 16)}}}
She used {{{1/8}}} of the number of bags.
