# How do you order the following from least to greatest 0.19, 0.09, 0.9, 1, 0?

$0 , .09 , .19 , .9 , 1$

#### Explanation:

We have these numbers to order from least to greatest:

$.19 , .09 , .9 , 1 , 0$

I find that dealing with decimals can get confusing sometimes, so I'm going to change them all to fractions. Since we have numbers that extend out to, at most, 2 decimal places, I'm going to multiply all of these numbers by $\frac{100}{100}$:

$.19 \left(\frac{100}{100}\right) = \frac{19}{100}$

$.09 \left(\frac{100}{100}\right) = \frac{9}{100}$

$.9 \left(\frac{100}{100}\right) = \frac{90}{100}$

$1 \left(\frac{100}{100}\right) = \frac{100}{100}$

$0 \left(\frac{100}{100}\right) = \frac{0}{100}$

And now we can reorder the numbers:

$\frac{0}{100} , \frac{9}{100} , \frac{19}{100} , \frac{90}{100} , \frac{100}{100}$

Putting them back in decimal form:

$0 , .09 , .19 , .9 , 1$
