Answer 1

Resposta:

Explicação passo a passo:

(mmc entre 3, 4 e 7 = 84)

(21+56+60)/84 =

137/84

h) 1/2+1/7+5/7

(mmc entre 2 e 7 = 14)

(7+2+10)/14 =

19/14

Answer 2

Resposta:

g)

$\frac{1}{4} + \frac{2}{3} + \frac{5}{7} = \\ \frac{21 + 56 + 60}{84} = \\ \frac{137}{84}$

h)

$\frac{1}{2} + \frac{1}{7} + \frac{5}{7} = \\ \frac{7 + 2 + 10}{14} = \\ \frac{19}{14}$

I)

$\frac{3}{7} + \frac{5}{2} + \frac{1}{14} = \\ \frac{6 + 35 + 1}{14} = \\ \frac{42}{14} = 3$
