What changes about the numbers when you go from one to the next, and what stays the same? Here, it looks like you start with the number 44, but how do you change the number from one to the next?
Okay. For each of those numbers, you are adding another zero behind the number, which means you are multiplying by 10. 44 * 10 is 440. 440 * 10 is 4,400. 4,400 * 10 is 44,000. And so on. The rule is that you are multiplying by 10.
The fact that it can turn its head 180 degrees is just extra information. They tell us that it is 10.5 cm long. What they're asking for is the length in a mixed number, so 10.5 as a mixed number.
