Problem number 9, Kanga wrote down a number and then covered each digit with a shape. She covered different digits by different shapes and the same digits by the same shape. Which number could be under the shapes shown to the right? A. 34426 B. 34526 C. 34423 D. 34424 E. 32446 If we look at the shapes here, we see that two of them are the same and then we have three different ones. So we are going to look and see which one has three different numbers and two of the same numbers right next to each other. So start off with A. So we have 3 and then we have 4, 4 and then we have a 2 and a 6. And there are two numbers right there and then we have three unique numbers there. So that could be our answer. If we look at this one, if we look at B, we have 3, 4, 5, 2, 6. That could not be our answer because all numbers are different and there are no repeats. If we look at 3, we have 3, 4, 4, 2, 3. This could not be our answer because we have a 3 there and a 3 there, so that could not be our answer. Then we have D with 3, 4, 4, 2, 4. This could not be our answer because there are three 4s. Then if we look at A, we have 3, 2, 4, 4, 6. This could not be our answer because the two 4s are further back, which means our answer is A.
