How many cups of cereal are in 10 servings? Move a number to each box to show the answer. If there is no whole number, move a 0 to the first box

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.
