Answer 1

Resposta:

Explicação passo-a-passo:

a)

$\frac{5}{3} +\frac{10}{15} =\frac{5}{3} +\frac{2}{3}=\frac{7}{3}$

b)

$\frac{8}{3} -\frac{2}{3}=\frac{6}{3} =2$

c)

$\frac{4}{5} +\frac{7}{6}=\frac{24+35}{30} =\frac{59}{30}$

d)

$\frac{9}{7} -\frac{2}{7}=\frac{7}{7} =1$

e)

$\frac{12}{9} +\frac{8}{3}=\frac{4}{3} +\frac{8}{3}=\frac{12}{3}=4$
