Question

A recipe for biscuits says to mix 6 cups of flour with 2 cups of milk.
How many cups of milk would you need for 5 cups of flour?

Answer 1

Answer:

$\frac{5}{3}$ or $1\frac{2}{3}$ cups of milk

Step-by-step explanation:

So if you have the ratio of 6 cups of flour to 2 cups of milk you can make this the fraction: $\frac{6}{2}$ and then for the 5 cups of flour to 'x' cups of milk the fraction would be: $\frac{5}{x}$

To solve for 'x', let the 2 fractions equal each other and cross multiply.

$\frac{6}{2} = \frac{5}{x}$

$x = \frac{2*5}{6} = \frac{10}{6} = \frac{5}{3} = 1\frac{2}{3}$

So you would need $\frac{5}{3}$ or 1 and $\frac{2}{3}$ cups of milk for 5 cups of flour.
