2. \begin{aligned}
(0.34\overline{67} + 0.13\overline{33}) = ?
\end{aligned}

  • \begin{aligned} 0.048\overline{01} \end{aligned}
  • \begin{aligned} 4.8\overline{01} \end{aligned}
  • \begin{aligned} 48.\overline{01} \end{aligned}
  • \begin{aligned} 0.48\overline{01} \end{aligned}

Answer: Option D

Explanation:

\begin{aligned}
(0.34\overline{67} + 0.13\overline{33})\end{aligned}
\begin{aligned} =
\frac{3467-34}{9900} + \frac{1333-13}{9900}
\end{aligned}
\begin{aligned}
= \frac{3433 + 1320}{9900}
= \frac{4753}{9900}
\end{aligned}
\begin{aligned}
= \frac{4801 - 48}{9900}
= 0.48\overline{01}
\end{aligned}
