Final answer:
To represent one third gallon of water in a 3 gallon container, we can use a division equation: x ÷ 3 = 1/3.
Step-by-step explanation:
For the situation of one third gallon of water in a 3 gallon container, we can represent it using:
a) A multiplication equation: 3 x x = 1/3
b) A division equation: x ÷ 3 = 1/3
To solve this type of problem, we need to set up a proportion. We know that 1 gallon is equal to 3 quarts, so 3 gallons would be equal to 3 x 3 = 9 quarts. The unknown quantity in this case is x, which represents the number of quarts. So the division equation x ÷ 3 = 1/3 would be the correct representation for the situation.
