45 cups of peaches are required to make 9 peach pies.

Step-by-step explanation:

We are given the following information:

2 pies were made from 10 cups of peaches

3 pies were made from 15 cups of peaches

4 pies were made from 20 cups of peaches

We need to find number of cups of peaches required to make 9 pies.

We could solve this problem by calculating the ration of peach pies to number of cups of peaches.

Ratio = Number of Pies:Number of cups of Peaches

$\displaystyle\frac{\text{Number of pies}}{\text{Number of cuos of peaches}} = \displaystyle\frac{2}{10} = \displaystyle\frac{3}{15} = \displaystyle\frac{4}{20} = 1:5$

Let x number of cups of peaches be required to make 9 pies. Then,

$\displaystyle\frac{1}{5} = \displaystyle\frac{9}{x}\\\\x = 9\times 5 = 45$

Thus, 45 cups of peaches are required to make 9 peach pies.
