Answer 2

а) $\frac{3}{5} -\frac{1}{4} +\frac{1}{3} =\frac{12*3-15+20}{60} =\frac{36-15+20}{60} =\frac{56-15}{60} =\frac{41}{60}$

б) $\frac{1}{3} -\frac{1}{9}+\frac{1}{6}=\frac{18-6+9}{54} =\frac{21}{54} =\frac{7}{18}$

в) $(\frac{2}{3} +\frac{1}{9}) -\frac{13}{18}=(\frac{6+1}{9} )-\frac{13}{18} =\frac{7}{9} -\frac{13}{18} =\frac{14-13}{18} =\frac{1}{18}$

г) $\frac{3}{4} -\frac{1}{2} +\frac{7}{8}=\frac{6-4+7}{8} =\frac{9}{8} =1\frac{1}{8}$

д) $\frac{5}{6}-\frac{2}{3}+\frac{1}{4} =\frac{20-16+6}{24} =\frac{10}{24} =\frac{5}{12}$

е)$\frac{1}{3} -(\frac{1}{9} +\frac{1}{6})=\frac{1}{3} -(\frac{2+3}{18} )=\frac{1}{3}-\frac{5}{18}=\frac{6-5}{18} =\frac{1}{18}$
