Answer:

The value of given expression is 0, where m=21 and n=12.

Explanation:

The given expression is

$\frac13m-1-\frac12n$

substitute m=21 and n=12 in the above expression.

$\frac13m-1-\frac12n=\frac13(21)-1-\frac12(12)$

$\frac13m-1-\frac12n=7-1-6$

$\frac13m-1-\frac12n=7-7$

$\frac13m-1-\frac12n=0$

Therefore the value of given expression is 0, where m=21 and n=12.
