Three friends share a pizza cut into 12 slices. Alice eats twice as many slices as Bob, and Charlie eats three times as many slices as Bob. How many slices does Alice eat?
4 slices
Let Bob's slices be x. Alice has 2x, Charlie has 3x. Total slices = x + 2x + 3x = 6x = 12, so x = 2. Alice eats 2 * 2 = 4 slices.
