To find the amount of water needed for 25 teaspoons of ammonia, we can set up a proportion based on the given information:
5 gallons of water requires 10 teaspoons of ammonia
x gallons of water requires 25 teaspoons of ammonia
5/10 = x/25
Cross multiplying, we get:
10x = 125
Dividing by 10 on both sides, we get:
x = 12.5
Therefore, 12.5 gallons of water are needed for 25 teaspoons of ammonia.
