First lets convert the pints to cups.
1 pint = 2 cups
12 pints = ? cups
Now lets multiply to find out how many cups are in 12 pints.
12 × 2 = 24
24 cups in 12 pints.
Now lets look at the information we have.
4 cups of water per 9 servings
Now lets divide to see how many time 24 goes into 4.
24 ÷ 4 = 6
Now lets multiply:-
6 × 9 = 54
So, 54 servings of water fir in 12 pints of water.
