Answer:
28 Gallons
Explanation:
This one is really easy, so i want you to look at my steps:
1. Gather all given information, container is 3/4, 7 gallons are poured out to make it 1/2 full.
2. Find a common denominator for the fractions 1/2 and 3/4, this would be 4.
3. Make them both the same denominator, 2/4 and 3/4.
4. Subtract the remaining amount from the original amount to see how much 7 gallons made up, 3/4 - 2/4 = 1/4
5. Now that you know that 7 gallons made up 1/4 of the container, you can just multiply 7 by 4 to get the total amount of gallons that can fit in the container.
7 * 4 = 28 gallons is the max that the container can hold.
