1. Mrs. Jones picks 3 flowers a day starting on Monday. How many does she have by Sunday? 2. 603 cats have 4 kittens each. How many kittens are there in total?

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.
