The examples can be: #0.90# and #0.900#

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=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:

#9/10=90/100=900/1000# and so on.

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