So we know that 3 pies want 7 cups of flour to be made. The number of pies that we can cook with 28 cups of flour lets call it X because its unknown. 

Lets try to create a simple ratio and lets cross multiply to find the result of it.

If 3 pies want 7 cups.

Then X pies want 28cups.

Lets cross multiply, so 7 times x is equal to 3 times 28.

7x=3*28

7x=84

Divide both sides with 7.

7x/7 = 84/7

x=12
