Week 16: Repeating Decimals

Repeating decimals is pretty simple to understand.
Every repeating decimal is the sum of an infinite geometric series.
so what you do is write the decimal as a quotient of fraction intergers
so if it was .3333333
it would be 1/3

So the steps are
1. write as a geometric series
2. find the sum with asub1/1-r r is what you multiple by.
Above are two examples adn how you solve it. 
you turn it into a fraction and it would be growing in the denominator and then you find out what r is and then you plug it into the sum equation to find out what the sum would be. then you find what the sum would be in fraction form.
SImple enough.
Hope you understand.

SEE YOU NEXT TIME!
