Answer:
1.

2.

Explanation:
Mix Y:
6 cups of concentrate + 8 cups of water
The ratio of concentrate to water is

Suppose you were making only 1 cup of mix Y.
Then
Amount of concentrate = 3x cup
Amount of water = 4x cup
Altogether = 1 cup,

Mix W:
3 cups of concentrate + 6 cups of water
The ratio of concentrate to water is

Suppose you were making 2 cups of mix Y.
Then
Amount of concentrate = x cups
Amount of water = 2x cups
Altogether = 2 cups,
