a) [tex]1\frac{1}{4} + \frac{2}{7} = \frac{5}{4} + \frac{2}{7} = \frac{35}{28} + \frac{8}{25} = \frac{43}{28} = 1\frac{15}{28}[/tex]
b) [tex]1\frac{3}{5} + 3\frac{3}{4} = 1\frac{12}{20} + 3\frac{15}{20} = 4\frac{27}{20} = 5\frac{7}{20}[/tex]
c) [tex]5\frac{2}{3} - 3\frac{3}{5} = 5\frac{10}{15} - 3\frac{9}{15} = 2\frac{1}{15}[/tex]
d) [tex]6\frac{1}{8} - 5\frac{3}{4} = \frac{49}{8} - \frac{23}{4} = \frac{49}{8} - \frac{46}{8} = \frac{3}{8}[/tex]
