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)

1 answer

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.
