a) \(0,\left( {37} \right){\rm{ }} + {\rm{ }}0,\left( {62} \right) \)
\(=0,\left( {01} \right).37 + 0,\left( {01} \right).62 \)
\(\displaystyle = \frac{1}{{99}}.37 + \frac{1}{{99}}.62\)
\(\displaystyle = {{37} \over {99}} + {{62} \over {99}} = {{99} \over {99}} = 1\)
b) \(\displaystyle 0,\left( {33} \right).3{\rm{ }}\)
\(\displaystyle =0,\left( {01} \right).33.3 = \frac{1}{{99}}.33.3\)
\(\displaystyle = {{33} \over {99}}.3 = {{99} \over {99}} = 1\)
