Question

Write numbers for the following vinculum numbers :

$5\overline{6}$

Answer 1

Finding the number for the given vinculum number:

A negative base to a number is the multiple of $10$ which is just smaller than the number.

Nearest negative base to $5\overline{6}$ $=50$

and the unit's digit is $6$

subtract the unit digit from the base i.e. $50-6=44$

Hence, the number for vinculum $5\overline{6}$ is $44$.
