Question

Meryl needs to cut down 10.5 trees for every 5 cabins she builds. How many trees will she need to cut down if she builds 3 cabins?

Answer 1

6.3 trees.

Explanation:

We have been given that Meryl needs to cut down 10.5 trees for every 5 cabins she builds.

Let us find the number of trees Meryl needs to cut down to build 1 cabin by dividing 10.5 by 5.

`\text{Number of tress needed to build 1 cabin}=(10.5)/(5)`

`\text{Number of tress needed to build 1 cabin}=2.1`

Now let us multiply 2.1 by 3 to find the number of trees Meryl needs to cut down to build 3 cabins.

`\text{Number of tress needed to build 3 cabins}=2.1* 3`

`\text{Number of tress needed to build 3 cabins}=6.3`

Therefore, Meryl needs to cut down 6.3 trees, if she builds 3 cabins.
