SP #6: Unit K Concept 10 - Writing repeating number as rational number using geometric series

     The viewer needs to pay special attention that this number is INFINITE, meaning it is continuous and has a repeating integers. With infinite numbers, the infinite sign is needed on top of the repeating numbers. One must also need to pay attention that the process of infinite geometric series is being used, which includes  summation notation, plugging it to the formula (a sub one divided by one minus r), and the sum. One last thing to remember before finding the final sum is to add the value on the left side of the decimal (which we ignored from the start) from the original.
