Answer 2

Respuesta:

$d. (\frac{6}{5} .\frac{10}{2} ) + (\frac{8}{10} .\frac{5}{2} ) = (\frac{3}{1} .\frac{2}{1} ) + (\frac{4}{2} .\frac{1}{1} ) = 6 + 2 = 8$

$e. (\frac{1}{2} +\frac{2}{5}+\frac{3}{10} ) . (\frac{3}{4} +\frac{1}{12} -\frac{1}{6} ) = (\frac{5+4+3}{10} ) . (\frac{9+1-2}{12} ) = \frac{12}{10} .\frac{8}{12} =\frac{1}{5} .\frac{4}{1} =\frac{4}{5}$

$f. (\frac{11}{3} +\frac{5}{9} -\frac{1}{6} +\frac{6}{3} ) - (\frac{4}{3} .\frac{1}{7} ) = (\frac{66+10-3+36}{18} ) + \frac{4}{21} = \frac{109}{18} +\frac{4}{21} =\frac{763+24}{126} =\frac{787}{126}$
