$7 \frac{1}{2}$

$\red{\underline{\underline {Step-by-step\: explanation:}}}$

We are given,

▪A = -1

▪B = -2

▪C = -3

∴ The value of,

$3ab + \frac{c}{2a} \\ ⇒3 \times ( - 1) \times ( - 2) + \frac{( - 3)}{2 \times ( - 1)} \\ ⇒6 + \frac{ - 3}{ - 2} \\ ⇒6 + \frac{3}{2} \\ ⇒ \frac{12 + 3}{2} \\ ⇒ \frac{15}{2} \\ ⇒7 \frac{1}{2}$
