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

Answer 1

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.
