Answer 1

Respuesta:

        a - C                                 b - A                                   c - B

   $1.\overline3*\cfrac{3}{5}~=\cfrac{4}{5}$                       $2.4\div \cfrac{4}{3}~=\cfrac{9}{5}$                      $0.6*\cfrac{1}{3}~=\cfrac{1}{5}$

Explicación paso a paso:

a)                                                                  b)

    $1.\overline3*\cfrac{3}{5}\\\\\cfrac{13-1}{9}*\cfrac{3}{5}\\\\\cfrac{12}{9}*\cfrac{3}{5}\\\\\cfrac{12*3}{9*5}~=\cfrac{36}{45}~=\cfrac{4}{5}$                                       $2.4\div \cfrac{4}{3}\\\\\cfrac{24}{10}\div \cfrac{4}{3}\\\\\cfrac{12}{5}*\cfrac{3}{4}\\\\\cfrac{12*3}{5*4}~=\cfrac{36}{20}~=\cfrac{9}{5}$

c)

   $0.6*\cfrac{1}{3}\\\\\cfrac{6}{10}*\cfrac{1}{3}\\\\\cfrac{6*1}{10*3}~=\cfrac{6}{30}~=\cfrac{1}{5}$
