How much mix and water make 14pancake if 2cups of mix and 3cups of water can make 18pancake

To solve this question is it easiest to work out the amount of mix and the amount of water separately: 

Mix
2 cups of mix = 18 pancakes

determine how many cups of mix would be in 1 pancake: 

2 ÷ 18 = 0.1111111
0.1111111 cups of mix = 1 pancake

You can then determine how many cups on mix will be needed for 14 pancakes:

0.111111 X 14 = 1.5 (1 and a 1/2 cups)

Water:
3 cups of water = 18 pancakes 

determine how many cups of water would be in 1 pancake: 

3 ÷ 18 = 1.6666666
1.6666666 cups of milk = 1 pancake

You can then determine how many cups on water will be needed for 14 pancakes:

1.666666 X 14 = 2.3 (2 and 1/3 cups)
