Como resuelvo esta fracción ( 1 3/7+3/4) +( 6/11+4/9) - ( 1 2/3 - 4/5) =

Answer 1

Explicación paso a paso:

$(1 \frac{3}{7} + \frac{3}{4} ) + ( \frac{6}{11} + \frac{4}{9} ) - (1 \frac{2}{3} - \frac{4}{5} ) = \\ \\ ( \frac{7 \times 1 + 3}{7} + \frac{3}{4} ) + ( \frac{54 + 44}{99} ) - ( \frac{3 \times 1 + 2}{3} - \frac{4}{5} ) \\ \\ ( \frac{10}{7} + \frac{3}{4} ) + \frac{98}{99} - ( \frac{5}{3} - \frac{4}{5} ) \\ \\ (\frac{40 + 21}{28} ) + \frac{98}{99} - ( \frac{25 - 12}{15} ) \\ \\ \frac{61}{28} + \frac{98}{99} - \frac{13}{15} = \\ \\ ( \frac{30.195 + 13.720 - 12.012}{13.860} ) = \frac{31.903}{13.860}$
