First compute the difference: $5 - 4 = 1$. Then take the absolute value: $|1| = 1$.

Compare positions: $\dfrac{9}{5} = 1.8$, $-\dfrac{2}{3} \approx -0.67$, $\dfrac{5}{8} = 0.625$, and $-\dfrac{7}{12} \approx -0.58$. The greatest is $\dfrac{9}{5}$.

Result: $4.1$.

Multiply by the reciprocal: $\dfrac{3}{4} \times \dfrac{3}{2} = \dfrac{9}{8} = \dfrac{9}{8}$.

Absolute value gives the non-negative distance from $0$, so $|-3| = 3$.

Distance from zero is absolute value: $\left|-\dfrac{23}{8}\right| = \dfrac{23}{8}$.

$5.70 \times 5 = 28.5$.

Multiply across: $\dfrac{3 \times 6}{6 \times 7} = \dfrac{18}{42} = \dfrac{3}{7}$.
