Question

How does writing 3.441 in expanded form show why the same digit can have different values?

Answer 1

When expanded it would be 3+0.4+0.04+0.001. There is two fours, but because it is written in expanded form you can see that one is four tenths and the other is four hundredths. Although they are the same digit, you can see that they are different values, the way you wrote it helping you with that.
