Hey there!

Let's think of this with a simpler example. Let's say one package is 4 pounds and one is 2 pounds. How many times heavier is the first than the second?Well, two, because the first package is double the weight of the second package! It's twice as heavy! And to get to that number, we divide four by two!

So, in our actual problem, we just divide 3.92 (bigger package) by 2.8 (smaller package).

3.92÷2.8=1.4

So, the first package is 1.4 times heavier than the first one!

Have a wonderful day!

So, since the initial 32 are in the lake tagged and he captures 55, in which 5 are a part of the other 32, we can assume that there are 50 new bass and that added to the 32 is 82, so there are 82 tagged bass in the lake.
