A recipe for stir fry calls for 6 cups of rice for every 5 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.

Great job!
To find how many cups of rice they’d need for 15 cups of veggies, it can be helpful to first find the unit rate, or the amount of rice needed for 1 cup of veggies. Partition the number line to find the number of cups of rice needed for every 1 cup of veggies.
