David has three bags of groceries weighing a total of 25 1/2 pounds. two of the bags weight 7 5/8 pounds and 4 3/4 pounds. how much does the third bag weigh?

So, we need to add 7 5/8 and 4 3/4 together.

7 5/8 + 4 3/4 = 12 3/8. (If you want to know how I added that, comment below )

So, now we need to subtract 25 1/2 - 12 3/8.

25 1/2 - 12 3/8 = 13 1/8 ( If you want to know how I subtracted comment below)

13 1/8 is your answer

Glad I could help, and good luck!
