Answer 1

Resposta:

a) $\frac{14}{3} + \frac{85}{3} = \frac{14 + 85}{3} = \frac{99}{3} = 33$

b) $\frac{94}{5} - \frac{62}{5} = \frac{94 - 62}{5} = \frac{32}{5}$

c) $\frac{8}{6} + \frac{7}{4} = \frac{16+21}{12} = \frac{37}{12}$

d) $\frac{13}{9} - \frac{9}{2} = \frac{26 - 81}{18} = \frac{-55}{18}$
