Sue has 55 inches of ribbon. she wants to cut the ribbon into 6 equal pieces. how long will each piece be?

You know that Sue has 55 inches of ribbon. If she wants to split it into 6 EQUAL pieces, she has to divide. 55 divided by 6 is 9.7 . The 6 equal pieces will have to be 9.7 inches long.

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.
