Answer 1

Resposta:

a)

$\frac{1}{2} + \frac{3}{2} = \frac{4}{2}$  

b)

$\frac{2}{5} - \frac{1}{3} = \frac{6}{15} - \frac{5}{15} = \frac{1}{15}$

c)

$\frac{2}{3} + \frac{3}{4} + \frac{2}{6} = \frac{8}{12} + \frac{9}{12} + \frac{4}{12} = \frac{21}{12}$

d)

$\frac{6}{8} + \frac{3}{2} = \frac{12}{16} + \frac{24}{16} = \frac{36}{24}$

e)

$\frac{15}{7} + \frac{3}{7} + \frac{1}{7} = \frac{19}{7}$

f)

$\frac{10}{5} - \frac{3}{6} = \frac{60}{30} - \frac{15}{30} = \frac{45}{30}$

g)

$\frac{12}{6} - \frac{3}{8} = \frac{96}{40} - \frac{18}{40} = \frac{78}{40}$

h)

$\frac{7}{4} - \frac{8}{9} = \frac{63}{36} - \frac{32}{36} = \frac{31}{36}$
