Above in another activity you were introduced to the set we call Kaprekar's Digits. This time we will insert the digit 0 and call the set the augmented Kaprekar set.: {0, 1, 4, 6, 7}. You will be multiplying by numbers formed from that set: e.g. 10746, 41067, etc. As before, the set for the products will be {2, 3, 5, 8, 9}. Now the number of permutations for 5 things is 120, which is a bit boring to list out. Therefore, we will change our approach this time. Your task will be in the form of a traditional matching quiz. This means, we will list the permutations that work in the left column and the other factor in the right column. Once a match has been made, those numbers can be set aside and considered as completed. There is another difference this time. The second factor will not be a whole number. Instead it will be nonintegral, greater than 1. An improper fraction if you prefer. This proved to be necessary due to the nature of the digits used. So let's go. Match them up!
