Question

If 28 dog biscuits weigh 12 1/4

A) 3/7 of an ounce
B) 4/5 of an ounce
C) 7/16 of an ounce
D) 7/28 of an ounce

Answer 1

`\large\boxed{C)\ (7)/(16)\ of\ an\ ounce}`

Explanation:

Divide the weight by the number of dog biscuits:

`\left(12(1)/(4)\right):28=(12\cdot4+1)/(4):28=(49)/(4):28=(1)/(28\!\!\!\!\!\diagup_4)\cdot(49\!\!\!\!\!\diagup^7)/(4)=(1)/(4)\cdot(7)/(4)=(7)/(16)`

Answer 2

Divide total weight by number of treats:

12 1/4 / 28 = 7/16

The answer is C.
