Answer 1

You will need 6 cups of sugar.

Step - by - Step Explanation

What to find? The number of cups of sugar needed to make a cake with 12 cups of flour.

Given:

Cups of flours = 4

Cups of sugar = 2

Cups of flour =12

Let x be the number of cups of sugar needed to make a cake with 12 cups of flour.

Using proportion;

4 cups of flour = 2 cups of sugar

12 cups of flour = x

Cross - multiply

4x = 24

Divide both-side of the equation by 4

$\frac{\cancel{4}x}{\cancel{4}}=\frac{24}{4}$

x =6

Hence, you will need 6 cups of sugar.
