If you divide 75 and 5 you would get 15. And then you would multiply 15 to 8 to get 120.
You would divide 75 and 5 because you’ll need to find how many minutes the caterpillar ate on one leaf which would be 15 minutes. You would then multiply 15 and 8 and you’d get 120. So, 120 leaves is the answer.
