mario took inventory of fish food in his store. there were 1 5/8 pounds of goldfish food, 9/16 pounds of beta food, and 17/20 pounds of tropical fish food. about how many pounds of fish food were there in all?
3 pounds
2 1/2 pounds
2 pounds
1 1/2 pounds

The answer is about 3. You find a common denominator of 80 and add 130/80+45/80+68/80 to get 243/80 which equals 3.0379
