Answer 1

$d)\ (- \frac{7}{6})-(+ \frac{11}{9})= -\frac{7}{6}-\frac{11}{9}= -\frac{21}{18}-\frac{22}{18}= \frac{-21-22}{18}= -\frac{43}{18}\\ \\e)\ (- \frac{7}{3})-(- \frac{5}{2})= -\frac{7}{3}+\frac{5}{2}= -\frac{14}{6}+\frac{15}{6}= \frac{-14+15}{6}= \frac{1}{6}\\ \\f) \ (-6,41)-(+9,882)= -6,41-9,882= - 16,292$
