а)-1 7/9+(-2 11/12)=
б)6 1/6+(-2 2/7)=

Answer 1

$- 1 \frac{7}{9} + ( - 2 \frac{11}{12} ) = - 1 \frac{28}{36} - 2 \frac{33}{36} = - 3 \frac{61}{36} = - 4 \frac{25}{36}$

$6 \frac{1}{6} + ( - 2 \frac{2}{7} ) = 6 \frac{1}{6} - 2 \frac{2}{7} = 6 \frac{7}{42} - 2 \frac{12}{42} = 5 \frac{49}{42} - 2 \frac{12}{42} = 3 \frac{37}{42}$
