Answer: The third fish weighs 7 5/8 pounds
Step-by-step explanation:
Hi, to answer this question, first, we have to add the weights of both fishes.
9 5/8 + 6 1/4 = 9 5/8 + 6 2/8 = 15 7/8
Since the 3 fishes weight 23 1/2 pounds, we have to subtract the weight of the 2 fishes to the total.
23 1/2 -15 7/8= 23 4/8 - 15 7/8= 22 (8/8 +4/8) -15 7/8= 22 12/8 -15 7/8 = 7 5/8
The third fish weighs 7 5/8 pounds
