If a recipe calls for 2 cups of flour for every 3 cups of sugar, how much sugar do I need for 6 cups of flour?

To find out how much sugar is needed for 6 cups of flour, we can set up a proportion. The ratio of flour to sugar is 2:3.

Using the equation $\frac{2}{3} = \frac{6}{x}$, where x represents the amount of sugar needed for 6 cups of flour, we can solve for x.

By cross-multiplying, we get $2x = 18$.

So, $x = 9$.

You would need 9 cups of sugar for 6 cups of flour.
