5) [tex]\frac{3}{4} +\frac{3}{10}[/tex] = [tex]\frac{15+6}{20}[/tex] = [tex]\frac{21}{20}[/tex]
6) [tex]\frac{3}{5} -\frac{1}{3}[/tex] = [tex]\frac{9-5}{15}[/tex] = [tex]\frac{4}{15}[/tex]
7) [tex]\frac{3}{4} +\frac{2}{5} +\frac{1}{6}[/tex] = [tex]\frac{45+24+10}{60}[/tex] = [tex]\frac{79}{60}[/tex]
8) [tex]\frac{13}{2} -\frac{1}{4} -\frac{5}{6}[/tex] = [tex]\frac{78-3-10}{12}[/tex] = [tex]\frac{65}{12}[/tex]
9) [tex]-\frac{3}{12} -\frac{1}{8}[/tex] = [tex]\frac{-6-3}{24}[/tex] = [tex]-\frac{9}{24}[/tex]
10) [tex]-\frac{2}{11} +\frac{11}{2} -\frac{12}{11}[/tex] = [tex]\frac{-4+121-24}{22}[/tex] = [tex]\frac{93}{22}[/tex]
