Question

a recipe for stir fry calls for 8 cups of rice for every 6 cups of veggies. suppose a restaurant is making a large batch of stir fry using 15 cups of veggies. how much rice would they need? start by labeling the double number line with the cups of veggies and cups of rice that the recipe calls for.

Explanation:

Step1: Set up proportion

Let $x$ be the amount of rice needed. The proportion is $\frac{8}{6}=\frac{x}{15}$ since the ratio of rice to veggies should be the same.

Step2: Cross - multiply

$6x = 8\times15$
$6x=120$

Step3: Solve for $x$

$x=\frac{120}{6}=20$

Answer:

20
