¡Hola!.

Resolvemos.

a)

 \frac{2}{10} +  \frac{6}{100} <=== amplificamos x10

 \frac{2*10}{10*10} +  \frac{6}{100}

 \frac{20}{100} +  \frac{6}{100}

 \frac{26:2}{100:2}

 \frac{13}{50} <==== respuesta.

===================================

b)

0.2 =  \frac{2}{10}

 \frac{2}{10} +  \frac{7}{10} +  \frac{2}{100}

 \frac{2+7}{10} +  \frac{2}{100}

 \frac{9}{10} +  \frac{2}{100} <=== amplificamos x10

 \frac{9*10}{10*10} +  \frac{2}{100}

 \frac{90}{100} +  \frac{2}{100} <=== fracciones homogéneas.

 \frac{90+2}{100}

 \frac{92:2}{100:2}

 \frac{46:2}{50:2}

 \frac{23}{25} <==== respuesta.

=======================================

c)

0.36 =  \frac{36}{100}

0.05 =  \frac{5}{100}

Entonces.

 \frac{36}{100} +  \frac{2}{10} +  \frac{1}{100} +  \frac{5}{100} +  \frac{4}{10} +  \frac{35}{100}

 \frac{36}{100} +  \frac{1}{100} +  \frac{5}{100} +  \frac{35}{100} +  \frac{2}{10} +  \frac{4}{10}

 \frac{36+1+5+35}{100} +  \frac{2+4}{10}

 \frac{77}{100} +  \frac{6}{10} <=== amplificamos x10

 \frac{77}{100} +  \frac{6*10}{10*10}

 \frac{77}{100} +  \frac{60}{100}

 \frac{77+66}{100}

 \frac{143}{100} <==== respuesta
