?

Answer 1

a. total weight = 22.8125 pounds

b. 2 pounds 15 oz

Explanation:

His license only allows him to catch a 20 pounds fish. He catches 4 fishes with the following weight.

12 pounds 3 oz , 2 pounds 15 oz, 7 pounds 1 oz and 10 oz.

a. The total weight of fishes he caught is calculated when you add the whole weight of the 4 fishes. Firstly let's convert the oz to pounds

16 ounces = 1 pounds

29 ounces = ? pounds

cross multiply

29/16 = 1.8125 pounds

12 + 2 + 7 = 21 + 1.8125 = 22.8125 pounds

total weight = 22.8125 pounds

b. The total weight he caught is above what the license allows him. Therefore, 22.8125 - 20 = 2.8125 pounds. The fish that has such weight is the fish with 2 pounds 15 oz so, that is the fish he will throw back to the lake.
