Answer 1

Respuesta:

1.-

$\frac{5}{6} +\frac{7}{9}+\frac{4}{3} =\frac{15+14+24}{18} =\frac{53}{18}$

$\frac{5}{6} +\frac{7}{9} -\frac{1}{3} =\frac{15+14-6}{18} =\frac{23}{18}$

$\frac{2}{3} +\frac{11}{15} -\frac{1}{5} =\frac{10+11-3}{15} =\frac{18}{15}$

$\frac{8}{12} +\frac{2}{5}-\frac{1}{2} -\frac{1}{10} =\frac{40+24-30-6}{60} =\frac{28}{60}$

2.-

$\frac{2}{3} *\frac{5}{14}=\frac{10}{42}$

$\frac{4}{3}$÷$\frac{7}{11}$$=\frac{44}{21}$

$6*\frac{5}{4}$=29

$\frac{4}{3}$÷6=$\frac{4}{18}$

3.-

$\frac{6}{7} *(\frac{9}{4} +\frac{3}{8} )=\frac{6}{7}*(\frac{18+3}{8}) =\frac{6}{7} *\frac{21}{8} =\frac{126}{56}$

$(8+\frac{2}{5} )$÷$(6-\frac{9}{4} )$=$(\frac{40+2}{5})$÷$(\frac{24-9}{4})$=$\frac{42}{5}$÷$\frac{15}{4}$=$\frac{168}{75}$

$\frac{7}{9}$÷$\frac{4}{3} +\frac{8}{12}*\frac{2}{5}$=$\frac{21}{36}+\frac{16}{60}$=$\frac{105+48}{180} =\frac{153}{180}$

$\frac{8}{12} +\frac{2}{5}$÷$\frac{6}{7}$=$\frac{8}{12}+\frac{14}{30} =\frac{40+28}{60}=\frac{68}{60}$

$\frac{5}{6} +\frac{7}{9} *\frac{4}{3} -\frac{1}{2} =\frac{5}{6}+\frac{28}{27} -\frac{1}{2} =\frac{45+56-27}{54} =\frac{74}{54}$

$\frac{5}{6} +\frac{7}{9} *(\frac{4}{3} -\frac{1}{2} )=\frac{5}{6} +\frac{7}{9} (\frac{8-3}{6} )=\frac{5}{6}+\frac{7}{9}*(\frac{5}{6} ) =\frac{5}{6} +\frac{35}{54} =\frac{90+70}{108} =\frac{160}{108}$
