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.
