I hope its not too complicated

Step-by-step explanation:




Here's what I got for the first question.
Did you want answers for the second one? I couldn't read that part of the image very well, if you did.
There are no tanks with less than 30 fish, so the first two groups ( 20-24) and (25-29) aren't used.
There are 3 tanks with 30-34 fish.
There are 3 tanks with 35-39 fish.
There are 3 tanks with 40-44 fish.
There are 1 tanks with 45-49 fish.
Now drag the bars for each group to the number of tanks.
