To make lemonade, you need 6 lemons and 8 cups of water. How many lemons do you need if you have 24 cups of water?

If you are using 8 cups of water for 6 lemons, then the ratio is 8 cups per 6 lemons.

To find out how many lemons are needed for 24 cups of water, you can use proportions:

(8 cups / 6 lemons) = (24 cups / x lemons)

Cross-multiplying, we have:

8x = 6 * 24

8x = 144

Dividing both sides by 8, we get:

x = 18

Therefore, you would need 18 lemons if you have 24 cups of water.
