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: Find the ratio of rice to veggies

The ratio of rice to veggies in the recipe is $\frac{8}{6}=\frac{4}{3}$.

Step2: Set up a proportion

Let $x$ be the amount of rice needed for 15 cups of veggies. The proportion is $\frac{4}{3}=\frac{x}{15}$.

Step3: Solve the proportion

Cross - multiply: $3x = 4\times15$. So $3x=60$. Then $x=\frac{60}{3}=20$.
