Помгите пожалуйста. срочно надо

1) $\frac{13}{17} + \frac{5}{16} + \frac{4}{17} + \frac{7}{16} = ( \frac{13}{17} + \frac{4}{17} ) + ( \frac{5}{16} + \frac{7}{16} ) = 1 + \frac{12}{16} = 1 + 0,75 = 1,75$
2) $( \frac{11}{60} + \frac{9}{28} )+( \frac{5}{28} + \frac{19}{60} ) = ( \frac{11}{60} + \frac{19}{60} ) + ( \frac{9}{28} + \frac{5}{28} ) = \frac{1}{2} + \frac{1}{2} = 1$
3) $( \frac{29}{44} + \frac{1}{6}) - \frac{7}{44} = \frac{174-44}{264} - \frac{7}{44} = \frac{130}{264} - \frac{42}{264} = \frac{88}{264} = \frac{1}{3}$
4) $( \frac{5}{8} + \frac{19}{36} ) - \frac{1}{36} = \frac{5}{8} - \frac{19 - 1}{36} = \frac{1}{8} = 0,125$
5) $\frac{35}{68} -( \frac{1}{68} + \frac{7}{22} ) = \frac{35 - 1}{68} - \frac{7}{22} = \frac{21-7}{22} = \frac{2}{11}$
6) $\frac{14}{39} -( \frac{1}{12} + \frac{1}{39} ) = \frac{14 - 1}{39} - \frac{1}{12} = \frac{4-1}{12} = 0,75$
