Explanation:
If the mix ratio for certain chemical is 1:6 when it is mixed with water. This means that for every 1 gallon of the chemical, 6 gallons of water is required.
Therefore, the number of gallons of water that would be mixed with 1/2 gallon of the chemical becomes
1/2 × 6 = 3 gallons of water.
