Answer 1

Vamos a resolver cada uno de los problemas con sus proceso

• Problema 1

$\frac{6}{7} -\frac{1}{14} +\frac{3}{17} *\frac{17}{21}=\\\\ \frac{6}{7} -\frac{1}{14} +\frac{3*17}{21*17}=\\\\ \frac{6}{7} -\frac{1}{14} +\frac{1}{7}=\\\\\frac{12-1+2}{14} =\\\\\frac{13}{14}$

• Problema 2

$\frac{7}{30} *\frac{20}{28} +\frac{5}{6} -\frac{3}{4}=\\\\\frac{7*20}{30*28}+\frac{5}{6} -\frac{3}{4}=\\\\ \frac{7*2*2*5}{5*6*2*2*7}+\frac{5}{6} -\frac{3}{4}=\\\\ \frac{1}{6}+\frac{5}{6} -\frac{3}{4}=\\ \frac{5+1}{6} -\frac{3}{4}=\\\\1 -\frac{3}{4}=\\\\\frac{1}{4}$

• Problema 3

$\frac{20}{22} *\frac{15}{11} +\frac{18}{17} /\frac{9}{17}=\\\\\frac{20*15}{22*11} +\frac{18*17}{17*9}=\\\\\frac{150}{121} +2=\\\\\frac{150+2*121}{121} =\\\\\frac{392}{121}$

• Problema 4

$\frac{20}{25}/\frac{2}{5}-\frac{14}{16}/\frac{7}{8}=\\\\\frac{20*5}{25*2}-\frac{14*8}{16*7}=\\\\\frac{2*2*5*5}{5*5*2}-\frac{7*2*8}{2*8*7}=\\\\2-1=\\\\1$

• Problema 5

$\frac{9}{10} -\frac{14}{20} *\frac{16}{21} +\frac{1}{15} =\\\\\frac{9}{10} -\frac{14*16}{20*21} +\frac{1}{15} =\\\\\frac{9}{10} -\frac{2*7*2*2*2*2}{5*2*2*7*3} +\frac{1}{15} =\\\\\frac{9}{10} -\frac{2*2*2}{5*3} +\frac{1}{15} =\\\frac{9}{10} -\frac{8}{15} +\frac{1}{15} =\\\\\frac{9}{10} -\frac{7}{15} =\\\\\frac{27-14}{30}=\\\\\frac{13}{30}$

• Problema 6

$\frac{24}{25} * \frac{5}{8}- \frac{2}{26}/\frac{3}{13}=\\\\ \frac{24*5}{25*8} - \frac{2*13}{26*3}=\\\\ \frac{3}{5} - \frac{1}{3}=\\\\\frac{3*3-1*5}{15}=\\\\ \frac{4}{15}$
