a) [tex]4 - 1\frac{18}{13} = \frac{x}{y} \frac{34}{13} = 2\frac{8}{13}[/tex]
b) [tex]6\frac{1}{6} - 2 \frac{5}{6} =\frac{37}{6} - \frac{17}{6} = \frac{10}{3} = 3 \frac{1}{3}[/tex]
c) [tex]\frac{2}{3} + \frac{3}{4} = \frac{8+9}{12} = \frac{17}{12} = 1\frac{5}{12}[/tex]
e) [tex]\frac{5}{12} - \frac{1}{3} = \frac{5-4}{12} =\frac{1}{12}[/tex]
f) [tex]5\frac{1}{3} - 2\frac{7}{10} = \frac{16}{3} -\frac{27}{10} = \frac{79}{30} = 2\frac{19}{30}[/tex]
g) [tex]3\frac{2}{3} + 1\frac{1}{7} = (3+1)+(\frac{2}{3} +\frac{1}{7} ) = 4+\frac{17}{21} = 4\frac{17}{21}[/tex]
