Question

A recipe uses 2 cups of sugar for every 5 cups of flour. how much sugar is needed for 15 cups of flour

Answer 1

To find out how much sugar is needed for 15 cups of flour, you can set up a proportion based on the recipe.

The ratio of sugar to flour is given as 2 cups of sugar for every 5 cups of flour.

You can set up the proportion as follows:

\[
\frac{2 \text{ cups of sugar}}{5 \text{ cups of flour}} = \frac{x \text{ cups of sugar}}{15 \text{ cups of flour}}
\]

Now, cross-multiply to solve for \(x\):

\[
2 \times 15 = 5 \times x
\]

This simplifies to:

\[
30 = 5x
\]

Now, divide both sides by 5:

\[
x = \frac{30}{5} = 6
\]

So, you will need **6 cups of sugar** for 15 cups of flour.
