The weight of an object on the Moon is one-sixth that of its weight on Earth. If an object weighs 35 pounds on the Moon, write and solve a division equation to find its weight on Earth.

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.
