In a cleaning mixture, the amount of water is directly proportional to the amount of ammonium a mixed 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 and decimal form.

Answer 1

The ratio of water to ammonia is 5:10 or 1:2.

To find out how much water is needed for 25 teaspoons of ammonia, we need to set up a proportion:

1 gallon / 2 teaspoons = x gallons / 25 teaspoons

Cross multiplying, we get:

2x = 25

x = 25 / 2

x = 12.5

Therefore, 12.5 gallons of water are needed for 25 teaspoons of ammonia.
