I really need help with this question, and I want a explanation too. Don't answer the question if your not gonna say anything useful.

D

Step-by-step explanation:

The ratio of pear trees to apples trees is 2.5. This means that there are 2.5 times more apple trees than pear trees. Say there are 15 apple trees. We know that since the apple trees have to be 2.5 times more than the pear trees, we can just divide 15 by 2.5 to get an answer of 6 pear trees. On the other hand, if they told there are 5 pear trees, we could just multiply 5 by 2.5 to get 12.5 apple trees (if you can imagine a half of a apple tree ;) ).

So, if they give us a bunch of examples of how many of each type of tree there is, just see if there are 2.5 times more pear trees than apple in each example.

D is the only one that meets the criteria of the 2.5 ratio, since 14 * 2.5 = 35,

so that's our answer!

Hope this helps you! Have a great day! Give me Brainliest!

Cheers!
