Brandon makes lemon water by adding3/4 of a cup of sliced lemon to 2 cups of water. At this rate, how many cups of sliced lemon would he need to add to 12 cups of water?

To find out how many cups of sliced lemon Brandon would need to add to 12 cups of water, we can set up a proportion using the given ratio of lemon to water:

3/4 cups of lemon / 2 cups of water = x cups of lemon / 12 cups of water

Cross multiplying, we get:

(3/4) * 12 = 2 * x
9 = 2x
x = 4.5

Therefore, Brandon would need to add 4.5 cups of sliced lemon to 12 cups of water.
