Answer 1

a)

$( \frac{6}{5} - \frac{4}{7} ) + ( - \frac{7}{15} ) =$

$\frac{22}{35} - \frac{7}{15} = \frac{17}{105}$

b)

$( \frac{8}{9} + \frac{7}{11} ) - ( \frac{1}{9} ) =$

$\frac{151}{99} - \frac{1}{9} = \frac{140}{99}$

c)

$\frac{1}{9} + ( \frac{4}{7} - \frac{6}{5} ) =$

$\frac{1}{9} + ( - \frac{22}{35} ) =$

$\frac{1}{9} - \frac{22}{35} = - \frac{163}{315}$

d)

$( \frac{1}{2} - \frac{5}{6} ) - ( - \frac{1}{4} + \frac{7}{12} ) =$

$( - \frac{1}{3} ) - \frac{1}{3} = - \frac{2}{3}$

e)

$( - \frac{4}{9} + \frac{7}{3} ) + ( \frac{4}{5} - \frac{5}{6} ) =$

$\frac{17}{9} + ( - \frac{1}{30} ) =$

$\frac{17}{9} - \frac{1}{30} = \frac{167}{90}$
