about
This picture shows a problem from Unit K Concept 10 which is about how to write a repeating decimal as a rational number using geometric series. No calculator should be used. We must break the long repeated decimal into smaller sums which is circled in the picture as an example. Using that information, we will have a sub 1 and then figure out what the ratio is by taking any term and divide it by the proceeding one. This is an infinite geometric series because the numbers go forever.
What the reader needs to pay attention to
The reader should to pay attention to the steps and the descriptions because that is what will show the readers how to do the problem. The reader must have a knowledge on geometric series in order to understand the basic of this problem.
