Question
The simplest for of $1.\overline{6}$ is:

Answer

  1. $\frac{5}{3}$
    Solution:
    Let $\text{x}=1.\overline{6}$
    $\Rightarrow\text{x}=1.666 \ ...(\text{i})$
    $\therefore10\text{x}=16.666 \ ...(\text{ii})$
    On subtracting (i) from (ii), we get
    $9\text{x}=15$
    $\Rightarrow\text{x}=\frac{15}{9}=\frac{5}{3}$
    Hence, the correct option is (c).
