7 cups of flour ... 9 people

x cups of flour = ? ... 15 people

If you would like to know how many cups are needed to make a cake for 15 people, you can calculate this using the following steps:

7 * 15 = 9 * x / 9

x = 7 * 15 / 9

x = 35/3

x = 11 2/3 cups of flour

Result: 11 2/3 cups of flour are needed to make a cake for 15 people.
