Question

How do you write two decimals that is equivalent to 0.9?

Answer 1

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

Explanation:

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.
