Question
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.(1 point)
The ratio of water to ammonia in the mixture is 5 gallons to 10 teaspoons, which can be simplified to 1 gallon to 2 teaspoons.
Therefore, for 25 teaspoons of ammonia, we would need:
25 teaspoons / 2 teaspoons per gallon = 12.5 gallons
So, 12.5 gallons of water are needed for 25 teaspoons of ammonia.
