ITEM (B)

Explicação passo-a-passo:

$\mathtt{\red {1},\blue {3}33...\Rightarrow \: \frac{\red {1\blue {3}} - 1}{9}\Rightarrow \frac{12}{9} \Rightarrow \frac{12 \div 3}{9 \div 3} = \frac{4}{3} }$

$\mathtt{\red {0},\blue {6}66...\Rightarrow \: \frac{\red {0}\blue{6} - \red {0}}{9} \Rightarrow \frac{6 - 0}{9}\Rightarrow \frac{6}{9} \Rightarrow \frac{6 \div 3}{9 \div 3}\Rightarrow \frac{2}{3} }$

$\mathtt{ \frac{4}{3} + \frac{2}{3} } \\ \mathtt{ \frac{4 + 2}{3} } \\ \mathtt{ \frac{6}{3} } \\ \red {\mathtt{2}}$
