Question 2

1) 12 - 1 $\frac{5}{7}$ = 11 $\frac{7}{7}$ - $1 \frac{5}{7}$ = $10 \frac{2}{7}$

2) $\frac{6}{11}$ - 1 = $\frac{6}{11} - \frac{11}{11} = - \frac{5}{11}$

3) $5 * \frac{2}{15} - 2 = \frac{5}{1} * \frac{2}{15} - 2 = \frac{2}{3} - 2 = \frac{2}{3} - \frac{6}{3} = - \frac{4}{3} = -1 \frac{1}{3}$

4) $-7 * \frac{3}{14} + \frac{3}{16} * 8 = - \frac{7}{1} * \frac{3}{14} + \frac{3}{16} * \frac{8}{1} = - \frac{3}{2} + \frac{3}{2} = 0$

5) $( \frac{7}{11} - \frac{5}{22} ) * 2 = ( \frac{14}{22} - \frac{5}{22} ) * 2 = \frac{9}{22} * \frac{2}{1} = \frac{9}{11}$

6) $7 \frac{2}{9} * -3 = -( \frac{65}{9} * \frac{3}{1}) = - \frac{65}{3} = -21 \frac{2}{3}$

7) $(-3 \frac{1}{6} -1 \frac{3}{4} )* 2= (- \frac{19}{6} - \frac{7}{4} )* 2 = (- \frac{38}{12} - \frac{21}{12} ) *2= - \frac{59}{12} * \frac{2}{1} = - \frac{59}{6} = [tex]-9 \frac{1}{2}$

8) $3 \frac{4}{15} - 8 \frac{1}{12} + 1 \frac{7}{30} = \frac{49}{15} - \frac{97}{12} + \frac{37}{30} = \frac{196 - 485 + 74}{60} = - \frac{242}{60} = -4 \frac{1}{30}$

9) $-\frac{2}{3} * \frac{4}{7} * 1 \frac{1}{2} + \frac{4}{21} *3 = -1008 + \frac{4}{7} = - \frac{7052}{7} = -1007 \frac{3}{7}$

10) $(13-3 \frac{4}{11}) * 3 = \frac{106}{11} * 3 = \frac{318}{11} = 28 \frac{10}{11}$

11) $- \frac{1}{2} * 0,3*-5*-1 \frac{1}{3} = -( \frac{1}{2} * \frac{3}{10} * \frac{5}{1} * \frac{4}{3}) = 1$
