Answer 2

Explicação passo-a-passo:

$a)$

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

$mmc = > 6$

$\dfrac{3 + 4}{6}$

$\dfrac{7}{6}$

$b)$

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

$mmc = > 12$

$\dfrac{8 + 9}{12}$

$\dfrac{17}{12}$

$c)$

$\dfrac{3}{5} + \dfrac{7}{10}$

$mmc = > 10$

$\dfrac{6 + 7}{10}$

$\dfrac{13}{10}$

$d)$

$\dfrac{2}{4} + \dfrac{1}{6}$

$mmc = > 12$

$\dfrac{6 + 2}{12}$

$\dfrac{8}{12}$

$\dfrac{8 {}^{ \div 2} }{12 {}^{ \div 2} }$

$\dfrac{4}{6}$

$\dfrac{4 {}^{ \div 2} }{6 {}^{ \div 2} }$

$\dfrac{2}{3}$
