Question

3 3/8 + (-9 1/2) 2 1/3 + (-4 5/6) 1 1/2 + (-5 1/6) 3 2/15 + (-9 1/2)

Answer 1

$\displaystyle3\frac{3}{8} +(-9\frac{1}{2} )=\frac{27}{8} -\frac{19}{2} =\frac{27}{8} -\frac{76}{8} =-\frac{49}{8} =-6\frac{1}{8} \\2\frac{1}{3} +(-4\frac{5}{6} )=\frac{7}{3} -\frac{29}{6} =\frac{14}{6} -\frac{29}{6} =-\frac{15}{6} =-2\frac{3}{6} =-2,5\\1\frac{1}{2} +(-5\frac{1}{6} )=\frac{3}{2} -\frac{31}{6} =\frac{9}{6} -\frac{31}{6} =-\frac{22}{6} =-\frac{11}{3} =3\frac{2}{3} \\3\frac{2}{15} +(-9\frac{1}{2} )=\frac{47}{15} -\frac{19}{2} =\frac{94}{30} -\frac{285}{30} =-\frac{191}{30} =-6\frac{11}{30}$
