Answer 2

Explicação passo-a-passo:

tex]a)[/tex]

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

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

$\dfrac{7}{6}$

$b)$

$\dfrac{2}{3} + \dfrac{5}{6}$

$\dfrac{4 + 5}{6}$

$\dfrac{9}{6}$

$\dfrac{9 { }^{ \div 3} }{6 {}^{ \div 3} }$

$\dfrac{3}{2}$

$c)$

$\dfrac{1}{3} - \dfrac{1}{6}$

$\dfrac{2 - 1}{6}$

$\dfrac{1}{6}$

$d)$

$\dfrac{4}{5} - \dfrac{1}{10}$

$\dfrac{8 - 1}{10}$

$\dfrac{7}{10}$
