Salutations, guests of Mathland!
Today we will be learning a fairly simple topic - repeating decimals!
Examples of such decimals are:
.23232323....
.7777...
.417417417....
It is stated that every repeating decimal is the sum of an infinite geometric series.
To solve for the repeating decimal, you would first write the decimal as a geometric sum. Then you would find the sum.
The equation used in this case is a1/(1-r).
To find r, it would be the common difference or ratio between each number in the repeating decimal.
Below is an example:
That is all! See you next time!
