Solution

a) $\frac{5}{13} + \frac{4}{13} \Rightarrow \frac{9}{13}$

b) $\frac{15}{23} - \frac{11}{23} = \frac{4}{23}$

c) $\frac{3}{4} + \frac{3}{8} = \frac{6 + 3}{8} = \frac{9}{8}$

d) $\frac{8}{9} - \frac{4}{9} = \frac{5}{9}$

e) $\frac{12}{13} - \frac{5}{13} = \frac{7}{13}$

f) $\frac{3}{4} - \frac{3}{8} = \frac{6 - 3}{8} = \frac{3}{8}$

g) $9 \frac{1}{3} - 7 \frac{8}{9} = \frac{28}{3} - \frac{71}{9} \Rightarrow \frac{84 - 71}{9} = \frac{13}{9}$

h) $9 \frac{1}{2} - 8 \frac{3}{4} = \frac{19}{2} - \frac{35}{4} \Rightarrow \frac{38 - 35}{4} = \frac{3}{4}$

g) $3 \frac{3}{8} - 2 \frac{3}{4} = \frac{27}{8} - \frac{11}{4} \Rightarrow \frac{27 - 22}{8} \Rightarrow 58$
