Question

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

Answer 1

`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 `100/100`:

`.19(100/100)=19/100`

`.09(100/100)=9/100`

`.9(100/100)=90/100`

`1(100/100)=100/100`

`0(100/100)=0/100`

And now we can reorder the numbers:

`0/100, 9/100, 19/100,90/100,100/100`

Putting them back in decimal form:

`0,.09,.19,.9,1`
