The answer is: there is 89.2% of the dog food remaining.

Step-by-step explanation:

Given: 31 1/4 lbs of dog food.

In one week - 3 1/8 lbs was used.

To find the amount left, subtract:

31 1/4 - 3  1/8 =

30 5/4 - 3 1/8 =

30 10/8 - 3/8 =

27 7/8 remaining.

To find the percent left, divide:

27 7/8 / 31 1/4 =

27.875 / 31.25 = .892.

Multiply by 100 to get percent:

.892 * 100 = 89.2% remaining.
