Write 1/5 + 1/5^2 + 1/5^3 as a decimal.

I will start by simplifying some of those terms over there. Let's rerwite it as:

\({1\over5}+{1\over25}+{1\over125} \)

Notice, that this is the same as:

0.2 + 0.04 + 0.008

As you can see, they are all alone, and there will be no carryovers. Therefore it's simply 0.248. 

 

You may decide to solve the fraction, however you don't have to.
