Ms. Park bought 4 cakes to share for Adriana's birthday party. She is giving 2/5 of a cake to each person. How many people will be sharing the
cakes in total? Explain your reasoning.

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.
