Some decimals don't stop! They go on and on forever in reruns -- just like The Brady Bunch!
Here are some examples:
7.3333333... |
6.454545... |
2.018888... |
9.1234234234... |
Remember that the little "dot dot dot" means it goes on forever!
To save time and space, we have a special notation for these. We just write the repeating part once and put a bar over it.
Check it out:
7.3333333... | = | |
