brainiest please show your work I give you

First we need to figure out how many total ounces the fish weighs.
Since there is 16oz in a pound, we just need to multiply 31 by 16 which equals 496oz. We also need to add 12 because the fish weighed 31 pounds and 12oz.
496 + 12 = 508
Okay, so now that we have the total amount of ounces that the fish weighs, we can divide it by the average serving size (6oz)
508 ÷ 6 = 84.66666....
84.66666 can be rounded to 85
Therefore, the fish has about 85 servings
Hope this helps
