To make banana bread, Colin uses 3/4 of a cup of brown for every 2 cups of flour. How much brown sugar should Colin use to make

Lelechka [254]

$\frac{3}{8}$ cups of brown sugar needed for only 1 cup of flour

<em><u>Solution:</u></em>

To make banana bread, Colin uses $\frac{3}{4}$ of a cup of brown for every 2 cups of flour

To find: Amount of brown sugar should Colin use to make a small batch with only 1 cup of flour

Let "x" be the amount of brown sugar needed for only 1 cup of flour

From given information,

$\text{ 2 cups of flour } = \frac{3}{4} \text{ cup of brown sugar }$

$\text{1 cup of flour } = \text{ x cup of brown sugar }$

This forms a proportion and we can solve the sum by cross multiplying

$1 \times \frac{3}{4} = 2 \times x\\\\x = \frac{3}{8}$

Thus $\frac{3}{8}$ cups of brown sugar needed for only 1 cup of flour
