Answer 1

а)$\frac{7}{12} -\frac{3}{8} +2\frac{1}{6} =\frac{7(2}{12} -\frac{3(3}{8} +\frac{13(4}{6} =\frac{14}{24} -\frac{9}{24}+ \frac{52}{24} =\frac{57}{24} =\frac{19}{8} =2\frac{3}{8}$

б)$(8-3\frac{5}{7} )-2\frac{3}{14} =(\frac{8(7}{1} -\frac{26(1}{7} )-\frac{31}{14}=(\frac{56}{7}- \frac{26}{7} )-\frac{31}{14}=\frac{30(2}{7} -\frac{31(1}{14}=\frac{60}{14} -\frac{31}{14} =\frac{29}{14} =2\frac{1}{14}$
