SP6: Unit K Concept 10:Writing a repeating decimal as a rational number using geometric series

Things that need to be paid close attention to is how many zeros are in the series. They also need to include summation notation and make sure the decimals are converted. When writing out the series make sure you count after the repeating numbers you add the zeros. So after .37 it would be .0037 taking the space of the previous .37 then the repeat. When there is a whole number at the beginning make sure to add it at the end by converting it by whatever the denominator is at the end.
