Answer:
174 15/16 lbs or 2799/16 lbs
Explanation:
to find the difference of the weight of the winning fish and the avg fish, I'm assuming you just need to subtract the values from each other.
so first I'm just gonna convert the mixed numbers into improper fractions because its easier to do math that way (for me).
342 5/16 = 5477/16 winning fish
167 3/8 = 1339/8 avg fish
now I need to find the difference between them so I'll just subtract the smaller number from the bigger number.
5577/16 - 1339/8 = difference
but wait oh no, they don't have the same denominator, so I'll multiply the 1339/8 by 2/2 so that I get a number over 16.
5577/16 - 2678/16 = difference
2799/16 lbs or 174 15/16 lbs (if you want to convert it into a nice mixed number)
