To find out how many cups of lemon juice are needed, we need to use the given ratio of lemon juice to water, which is 1:5. This means that for every 1 part of lemon juice, we need 5 parts of water.

Given that 15 cups of water are used to make a pitcher of lemonade, we can set up a proportion to solve for the number of cups of lemon juice:

1 part lemon juice / 5 parts water = lemon juice needed / 15 cups water.

To solve this proportion, we cross-multiply:

(1 part lemon juice) * (15 cups water) = (5 parts water) * (lemon juice needed).

15 cups water = 5 * lemon juice needed.

Dividing both sides of the equation by 5:

15 cups water / 5 = lemon juice needed.

3 cups = lemon juice needed.

Therefore, you would need 3 cups of lemon juice to make the pitcher of lemonade.
