Question

How are the decimals .009 and .09 related?

Answer 1

They're related only because they are smaller than .1. They both have 9 and both have at least on zero. They're different though because .09 is a larger number than .009

Answer 2

0.09 is ten times of 0.009

Explanation:

The two decimals are 0.009 and 0.09

We can rewrite the decimals in the scientific notation.

0.009 =
`9* 10^(-3)`

And 0.09 =
`9* 10^(-2)`

Now we divide first decimal 0.09 by 0.009

`(0.09)/(0.009)=(9* 10^(-2) )/(9* 10^(-3) )`

=
`(10^(-2))/(10^(-3))`

=
`(10^(3) )/(10^(2) )=10`

Therefore, 0.09 is ten times of 0.009
