BAKING A recipe that will make 3 pies calls for 7 cups of flour. Find how many pies can be made with 28 cups of flour.

12 pies

Step-by-step explanation:

To solve this problem, the best method will be to use a proportion! To set this proportion up, you must understand the values that the problem is giving you. The problem states that 7 cups of flour makes 3 pies. This wording tells us that those two values will both be on one side of the proportion. It does not matter which value is on top or bottom, as long as they are together on one side! For this problem, I'll set up the left side of the proportion like this:

Next, you'll include your third value and your x on the right side of the proportion. Make sure that your third value aligns with its matching value on the other side. For example, since our third value here is the 28 cups of flour, it must be on the bottom on the right side since your 7 cups of flour is on the bottom of the left side. This is what the proportion should now look like:

To solve, just cross multiply and divide! 3 times 28 is 84. Then, divide the 84 by the 7 and you'll get a final answer of 12 pies!
