6. To clean his floors, Larry uses a recipe for a homemade cleaner of 1 part lemon juice, 1 part vinegar, and 2 parts hot water. If he needs to mix 2 gallons of the cleaner and there are 16 cups in a gallon, how
much of each ingredient does he need?

8 cups lemon juice
8 cups vinegar
16 cups hot water

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
