Unit K Concept 10: writing a repeating decimal as a rational number using geometric series
When doing these problems remember to not worry about the number in front of the decimal right away: forget about it in the beginning. Since it is a 3 digit repeating decimal it goes on top of 1000 making r=1/1000. You solve it and plug it into the formula and one you get your answer you add it to the umber in front which you previously ignored in the beginning.
