Answer 1

Explicación paso a paso:

El proceso paso a paso es así

a) $\frac{7}{8} - \frac{5}{9} = \frac{(7*9) - (5*8)}{8*9} = \frac{63-40}{72} = \frac{23}{72}$

Los demás los hare directo:

b)$\frac{9}{6} - \frac{2}{3} = \frac{27-12}{18} = \frac{15}{18}$

c)$\frac{64-32}{16} = \frac{32}{16} = 2$

d) $\frac{16-7}{28} = \frac{9}{28}$

e)$\frac{8-15}{12} = \frac{-7}{12}$

f)$\frac{63-10}{18} = \frac{53}{18}$

g) $\frac{16-7}{28} = \frac{9}{28}$
