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.
Hope this helps!! Have an Awesome day!!! :-)
