In a cleaning mixture the amount of water is directly proportional to the amount of ammonia. A mix with 5 gallons of water requires 10 teaspoons of ammonia. How many gallons of water are needed for 25 teaspoons of ammonia? Write your answer in decimal form
The ratio of water to ammonia is 5 gallons to 10 teaspoons.
To find the amount of water needed for 25 teaspoons of ammonia, we can set up a proportion:
5 gallons / 10 teaspoons = x gallons / 25 teaspoons
Solving for x:
x = (5 gallons * 25 teaspoons) / 10 teaspoons
x = 12.5 gallons
Therefore, 12.5 gallons of water are needed for 25 teaspoons of ammonia.
