Question

Write vinculum number for the following number :

$76$

Answer 1

Finding the vinculum number of $76$:

Nearest positive base to $76$ $=80$

Subtract number from the base i.e. $80-76=4\left(extra\right)$

Now add base and extra i.e. $80+4=8\overline{4}$

Clearly, $8\overline{4}$ means that $4$ is taken away from $80$.

Hence, vinculum of $76$ is $8\overline{4}$ .
