Answer 1

Explicação passo-a-passo:

.

$\dfrac{6}{4} + \dfrac{1}{8} - \dfrac{3}{2}$

$\dfrac{6 \div 2}{4 \div 2} + \dfrac{1}{8} - \dfrac{3}{2}$

$\dfrac{3}{2} + \dfrac{1}{8} - \dfrac{3}{2}$

$0 + \dfrac{1}{8}$

$\dfrac{1}{8}$

.

$\dfrac{9}{5} - \dfrac{3}{4} + \dfrac{1}{7}$

$\dfrac{252 - 105 + 20}{140}$

$\dfrac{167}{140}$
