a menu which serves 4 people requires 3 cups of flour.how many cups of flour are needed for the menu to serve 12 people?

12/4 = 3 times as much

3 * 3 = 9

Direct or inverse??

To find out how many cups of flour are needed for the menu to serve 12 people, we can use a proportion.

We know that a menu serving 4 people requires 3 cups of flour. Let's set up the proportion:

(3 cups of flour) / (4 people) = (x cups of flour) / (12 people)

To solve for x (the number of cups of flour for 12 people), we can cross-multiply and then divide:

4 * x = 3 * 12

4x = 36

Dividing both sides by 4:

x = 36 / 4

x = 9

Therefore, for the menu to serve 12 people, you would need 9 cups of flour.
