Matt is planting fruit trees in his orchard. For every 3 apple trees, he plants 2 peach trees. If Matt wants 15 trees in all, how many apple trees will he plant? How many peach trees?

9 apple, 6 peach trees.

Step-by-step explanation:

Ratio of apple to peach trees is 3:2 so the number of apple trees is 3/5 of the total.

So the number of apple trees in 15 is 3/5 * 15 = 9 apple trees.

The number of peach trees will be 15 - 9 = 6.
