g)2/3 + 3/7 + 2/8=​

Answer 1

Explicação passo-a-passo:

D)

$\dfrac{5}{4} + \dfrac{10}{9}$

$\dfrac{45 + 40}{36}$

$\dfrac{85}{36}$

E)

$\dfrac{11}{19} + \dfrac{3}{19}$

$\dfrac{11 + 3}{19}$

$\dfrac{14}{19}$

F)

$\dfrac{10}{11} - \dfrac{5}{11} + \dfrac{7}{11}$

$\dfrac{10 - 5 + 7}{11}$

$\dfrac{12}{11}$

G)

$\dfrac{2}{3} + \dfrac{3}{7} + \dfrac{2}{8}$

$\dfrac{2}{3} + \dfrac{3}{7} + \dfrac{2 {}^{ \div 2} }{8 {}^{ \div 2} }$

$\dfrac{2}{3} + \dfrac{3}{7} + \dfrac{1}{4}$

$\dfrac{56 + 36 + 21}{84}$

$\dfrac{113}{84}$
