Before, I showed you
how to convert fractions to decimals... But, only
for certain, special kinds of fractions! These
fractions had denominators that were only made up of
2's and
5's. Like
To do these, you
turned those denominators into powers of 10 to convert
them to decimals.
Then, I told you that
you needed another method to convert something like
So, here is that
method! (Aren't you excited?)
To convert these
critters into decimals, we use long division to divide
the numerator by the denominator:
| Let's convert
|
|
to a decimal. |
Set it up and you'll
see that the 3 doesn't divide in right away... So,
we need to use our knowledge of decimal division!
Hey! We're stuck
in a repeating loop, aren't we?
Yep, these things
always convert into repeating decimals!
