Question

Jose mixed 3mL of a chemical solution with every gallon of water for his aquarium. Kevin mixed 6mL of a chemical solution with every 3 gallons of water for his aquarium.

Answer 1

the second one is the correct answer

Answer 2

The answer is the second option, as 6:3 is less than 3:1

Explanation:

• To work this out, divide Kevins' ratio by 3 to work out how much of the chemical solution he uses per gallon:

6:3 ÷ 3 = 2:1

• This shows that he uses less chemical solution per gallon than Jose, as 6:3 is less than 3:1.
