1. Infinite decimal expansions: We can interpret any finite decimal expansion as a finite sum. For example: \\[ 2.1309=2+\\frac{1}{10}+\\frac{3}{10^{2}}+\\frac{0}{10^{3}}+\\frac{9}{10^{4}} \\] Similarly, we can interpret any infinite decimal expansion as an infinite series. Interpret the following numbers as series, and add up the series to calculate their value as fractions: (a) \\( 0.99999 \\ldots \\) (b) \\( 0.11111 \\ldots \\) (c) \\( 0.252525 \\ldots \\) (d) \\( 0.3121212 \\ldots \\) Hint: use the geometric series formula.
