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
