Explicação passo a passo:

\mathsf{a)\:1,353535... + 0,232323 = 1,585858}

\mathsf{x = 1,585858}

\mathsf{100x = 158,5858}

\mathsf{100x - x = 158 - 1}

\mathsf{99x = 157}

\boxed{\boxed{\mathsf{x = \dfrac{157}{99}}}}

\mathsf{b)\:3,262626... + 1,555555 = 4,818181}

\mathsf{x = 4,818181}

\mathsf{100x = 481,8181}

\mathsf{100x - x = 481 - 4}

\mathsf{99x = 477}

\mathsf{x = \dfrac{477 \div 9}{99 \div 9}}

\boxed{\boxed{\mathsf{x = \dfrac{53}{11}}}}

\mathsf{c)\:2,444444... + 1,222222 = 3,666666}

\mathsf{x = 3,666666}

\mathsf{10x = 36,66666}

\mathsf{10x - x = 36 - 3}

\mathsf{x = \dfrac{33 \div 3}{9 \div 3}}

\boxed{\boxed{\mathsf{x = \dfrac{11}{3}}}}
