$\dfrac{7}{2} + ( \dfrac{4}{3} ) {}^{2} - \dfrac{1}{6}$

$\dfrac{7}{2} + \dfrac{16}{9} - \dfrac{1}{6}$

$\dfrac{63 + 32 - 3}{18}$

$\dfrac{92 {}^{ \div 2} }{18 {}^{ \div 2} }$

46/9

B)

$( - \dfrac{7}{9} ) \times \dfrac{2}{7} \times ( - \dfrac{1}{6} )$

$\dfrac{14 {}^{ \div 14} }{378 {}^{ \div 14} }$
