Binary numbers Humans use the ten digits 0 through 9 to form base- 10 or decimal numbers, whereas computers calculate and store numbers internally as binary numbers-numbers consisting entirely of O's and I's. For this exercise, we consider binary numbers that have the form $0 . b_{1} b_{2} b_{3} \ldots$ where each of the digits $b_{1}, b_{2}, b_{3}, \ldots$ is either O or 1 The base- 10 representation of the binary number $0 . b_{1} b_{2} b_{3} \ldots$ is the infinite series $\frac{b_{1}}{2^{1}}+\frac{b_{2}}{2^{2}}+\frac{b_{3}}{2^{3}}+\cdots$. Verify that the base- 10 representation of the binary number $0.010101 \ldots$ (which can also be written as $0 . \overline{01}$ ) is $\frac{1}{3}$
