Answer 2

$\mathtt{\dfrac{\frac{5}{4}-\frac{1}{8}}{\frac{2}{3}}\div\dfrac{1}{2}}$

$\mathtt{\dfrac{5}{4}-\dfrac{1}{8}=\dfrac{10-1}{8}=\dfrac{9}{8}}$

$\mathtt{\dfrac{\frac{9}{8}}{\frac{2}{3}}\div\dfrac{1}{2}}$

$\mathtt{\dfrac{\frac{9}{8}}{\frac{2}{3}}=\dfrac{9}{8}\times\dfrac{3}{2}=\dfrac{27}{16}}$

$\mathtt{\dfrac{27}{16}\div\dfrac{1}{2} = \dfrac{27}{16} \times 2 = \dfrac{27}{8} }$

$\huge\boxed{\boxed{\mathtt{\dfrac{\frac{5}{4}-\frac{1}{8}}{\frac{2}{3}}\div\dfrac{1}{2}=\dfrac{27}{8}}}}$
