An apple pie needs 10 large apples 2 crusts (top and bottom) and 1 tablespoon of cinnamon. Write a balanced equation that fits this situation. How many apples are needed to make 25 pies?

First, you have to make an equation which has all of the ingredients on one side and the final product on the other side.

The equation would be: 1 tb cinnamon + 2 crusts + 10 apples = 1 pie

To make 25 apple pies you have to multiply the whole equation by 25.

25 (1tb cinnamon + 2 crusts + 10 apples = 1 pie)

So you end up with:

25 tbs of cinnamon + 50 crusts + 250 apples = 25 pie

In other words, to make 25 pies you will need 25 tablespoons of cinnamon, 50 pie crusts, and 250 large apples.
