Answer 1

> Let's minus it.

Answer:

Let the number be added be x.

$x + (\frac{ - 3}{12}) = \frac{ - 1}{6} \\ x = \frac{ - 1}{6} - ( \frac{ - 3}{12}) \\ x = \frac{ - 1}{6} + \frac{3}{12} \: \: \: \: \: \\ x = \frac{ - 2 + 3}{12} \: \: \: \: \: \: \: \: \: \\ x = \frac{1}{12}$

$hence \: \frac{1}{12} must \: be \: added$
