If you mean 25% of the total hamsters then the answer is simple 100 divided by 25 equals 4 so you would multiply 4 times 8 to get your answer of 32. I hope that helps.
The small rectangle was blown up by 5 times to turn into the bigger rectangle to put x5 in the box =)
I think it is 3200 because you divide 8000 by 5 then multiply that by 2
