Step 1
Generally if you add zeros to the right side of a decimal you get the fractions equal to the original number:

0.9 = 0.90 = 0.900

To proove that let's change the decimals to fractions:

0.9 = \frac{9}{10}

We can expand the fraction by any number to get other equal fractions. If we expand them by the powers of 10 we get equal decimals:

\frac{9}{10} = \frac{90}{100} = \frac{900}{1000}

and so on.
From this we can see that if you add zeros to 0.9 you get equal decimals.
