c)
[tex] \frac{2323}{3232} + ( - \frac{4242}{2424}) = \frac{2323}{3232} - \frac{4242}{2424} = - \frac{33}{32} [/tex]
d)
[tex]( - \frac{123123}{222222}) + (- \frac{41041}{74074}) = (- \frac{123123}{222222} )- \frac{41041}{74074} = - \frac{41}{37} [/tex]
e)
[tex] \frac{2}{18} + ( - \frac{1}{6} ) + ( - \frac{3}{24} ) = \frac{2}{18} - \frac{1}{6} - \frac{3}{24} = - \frac{13}{72} [/tex]
f)
[tex] \frac{4}{5} + ( - \frac{5}{6} ) + \frac{6}{7} = \frac{4}{5} - \frac{5}{6} + \frac{6}{7} = \frac{173}{210} [/tex]
