Module 7 Lesson 9: Decimal Expansions of Fractions, Part 1 Concept Development No. To add 0. 83333333 … and ��. ������ …, we need to start by adding together their rightmost digits. But these decimals are infinitely long, and there are no rightmost digit. It is not clear how we can start the addition. Could you easily multiply the two decimals to find the expansion of their product? Thinking about how to multiply the two decimals, 0. 83333333 … and ��. ������ …, is even more confusing! CFU
