### Brendan's Blog Post for November 01, 2010

Thank you, Joshua for picking me to do this blog post.

Today in math class, we learned about converting decimals into fractions.

The first step to convert a decimal into a fraction is to find out how many times to multiply the decimal so that the repeating numbers line up.

For example, if you needed to convert the decimal "0.032" with 32 repeating you would do this.

100x = 3.232
x = 0.032

Notice that the repeating numbers line up ?
If you subtract the repeating number (x) from the multiplied number (100x), you get a non repeating number (99x), I think.

This step would look like this.

100x = 3.232
x = 0.032
---------------------
99x = 3.200

Now to get 99x to become just x, you have to divide it by 99.

And if you do one thing to one side, you have to do it to the other.

99x = 3.200
----- -------
99 99

After that, I came up with
x = 3.200
-------
99

The final step is to simplify.

3.200/99 is the same as saying 32/99 which is also the same as saying 16/495.

Thank you for reading my blog post.
Please do not be afraid to help me learn by correcting me or helping me do something different.

Sorry Brianna,

April is doing the blog next ! (=
