Answer 2

Explicação passo-a-passo:

$a)$

$\dfrac{9}{5} + \dfrac{3}{4}$

$\dfrac{36 + 15}{20}$

$\dfrac{51}{20}$

$b)$

$\dfrac{3}{5} + \dfrac{8}{5}$

$\dfrac{3 + 8}{5}$

$\dfrac{11}{5}$

$c)$

$\dfrac{5}{8} + \dfrac{3}{8} - \dfrac{4}{8}$

$\dfrac{5 + 3 - 4}{8}$

$\dfrac{4}{8}$

$\dfrac{4 {}^{ \div 4} }{8 {}^{ \div 4} }$

$\dfrac{1}{2}$
