Answer 1

Resposta:

a)$\frac{16}{12}$  

b)$\frac{2}{8}$  

c)$\frac{9}{18}$  

d)$\frac{21}{18}$

Explicação passo-a-passo:

a)1/2+5/6=                           b)3/4-1/2                    

$\frac{1}{2} +\frac{5}{6} =\frac{6+10}{12} =\frac{16}{12}$                $\frac{3}{4} -\frac{1}{2} =\frac{6-4}{8}=\frac{2}{8}$      

c)5/6-1/3

$\frac{5}{6}-\frac{1}{3} =\frac{15-6}{18} =\frac{9}{18}$

d)1/3+5/6

$\frac{1}{3}+\frac{5}{6} =\frac{6+15}{18}=\frac{21}{18}$
