Question

You use 8 cups of flour to make 24 muffins. At that rate how much flour will it take to make 30 muffins?

(Me and my friend have 2 different answers)

Answer 1

You have 8 cups of flour to 24 muffins, which can be shown as 8:24, or 8/24. You need to find x cups of flour to 30 muffins, which can be shown as x:30, or x/30. You will want to cross multiply.

8 x
-- * --
24 30

8 * 30 = 24 * x
240 = 24x
10 = x

You need 10 cups of flour.

Answer 2

For 24 muffins, you needed = 8 cups
So, for 1 muffin, it is = 8/24 = 1/3 cup

Now, for 30 muffins, it would be: 1/3 * 30 = 10

In short, Your Answer would be 10 cups

Hope this helps!
