If Ella needs to cut down 10.5 trees for every 5 cabins

Then for 10 and 15 we can multiply 10.5

10 divided by 2 is 5, so to find how many trees we need for 10 cabins, we can multiply the trees you need by 2

So 10.5 x 2 = 21

To build 10 cabins, Ella will need 21 trees

15 divided by 5 = 3 so to find how many tress we need for 15 cabins, we can multiply the trees needed by 3

So 10.5 x 3 = 31.5

To build 15 cabins, Ella will need to cut down 31.5 trees

I hope this helps! Please mark my answer as the brainliest if it was the best <3
