Answer:
4 7/10
Step-by-step explanation:
Anna bough 2 3/5 pounds of grapes, and Sanika bought 1/2 pounds less. You first need to find how much Sanika bought. First find a common denominator. We can use 10. The numbers become 2 6/10 and 5/10 less. We now know that Anna bough 2 6/10, and Sanika bough 2 1/10. Therefore, they bought a total of 4 7/10's pounds.
