B)1/2+1/3+1/5
C)5/6+3/5
D)1/2-1/3_1/6

Answer 1

Resposta:

a)$\frac{19}{12}$

b)$\frac{31}{30}$

c)$\frac{43}{30}$

d)0

Explicação passo-a-passo:

A) $\frac{3}{4} + \frac{5}{6}$ = ?

    $\frac{9+10}{12}$ = $\frac{19}{12}$

B) $\frac{1}{2} + \frac{1}{3} + \frac{1}{5} = ?$

  $\frac{15+10+6}{30}$ = $\frac{31}{30}$

C) $\frac{5}{6} + \frac{3}{5} = ?$

   $\frac{25+18}{30}$ = $\frac{43}{30}$

D) $\frac{1}{2} - \frac{1}{3} - \frac{1}{6}=?$

      $\frac{3-2-1}{6}$ = $0$
