Answer and Explanation:

Given : Number 3.441

To find : How does writing number in expanded form show why the same digit can have different values?

Solution :

Writing number in expanded form,

[tex]3.441=3\times 1+4\times \frac{1}{10}+4\times \frac{1}{100} +4\times \frac{1}{1000}[/tex]

or [tex]3.441=3\times 1+4\times10^{-1}+4\times10^{-2}+4\times 10^{-3}[/tex]

The same digit 4 have different values because their place values are different as tenths and hundredths so their face value change.

As tenth place 4 is 0.4 and hundredths place 4 is 0.04.
