Question

Write vinculum number for the following numbers :

$48$

Answer 1

Finding the vinculum number of $48$:

Nearest positive base to $48$ $=50$

Subtract number from the base i.e. $50-48=2\left(extra\right)$

Now add base and extra i.e. $50+2=5\overline{2}$

Clearly, $5\overline{2}$ means that $2$ is taken away from $50$.

Hence, vinculum of $48$ is $5\overline{2}$ .
