To make lemonade, use 1 cup of lemon juice for every 3 cups of water. if you use 12 cups of water, how many cups of lemon juice will you need? use a double number lineto solve.

4 cups of lemon juice is required for 12 cups of water to make lemonade.

Step-by-step explanation:

Given:

To make lemonade 1 cup of lemon juice is required with 3 cups of water.

To find how many cups of lemon juice is required with 12 cups of water.

Solution:

We will construct a double number line of which one represents the cups of lemon juice and the other represents the cups of water.

From the number lines we can see that with 1 cup of lemon juice there are 3 cups of water.

So, ratio of cups of lemon juice to cups of water = 1 : 3

If we require cups of lemon juice with 12 cups of water then ratio = x : 12

Since ratio will always be equivalent, so we can write it as:

Multiplying both sides by 12.

∴

Thus, 4 cups of lemon juice is required for 12 cups of water to make lemonade.
