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


In this student problem we had to create a problem form concept 10. First our problem had to have 2 or 3 repeating numbers and a  whole number before the decimal. After that we had to use the formula a sub infinity equals a sub 1 over 1 minus r. We also had to include the proper notation. The trickest part of these types of problems is that we have to be careful with the fractions. You make to make sure you convert you decimals into fractions correctly or the whole thing will be wrong. Lastly you need to watch out for the number before the decimal. Do not forget to add it at the end of your problem. Thank you for viewing!
