Answer 2

@Az

Answer 3

So how many fishes are there total in the sample they collected?

52 + 61 + 87 = ??

and then how many of those are bluegills? 87 of them

so do 87 / (that number you just found when you added all the number of fishes)

Answer 4

Okay

Answer 5

this gets your probability of bluegill fishes**

Answer 6

@az its 200

Answer 7

Good and so when they caught 200 fishes, 87 of them were bluegills

87 / 200

so you can just divide that and then multiply by 800 fishes to see how many would be bluegills

or if you notice the ratio

87 bluegills among 200 fishes
?? bluegills among 800 fishes

just multiply 87 by 4

Answer 8

Soo 348

Answer 9

Okay, so it is D, thanks again for the explanation.
