Answer:

Value of the expression is 0

Step-by-step explanation:

[tex]\frac{1}{3} m -1-\frac{1}{2} n[/tex]

Given the value of m and n

m= 21  and n= 12

We plug in the value of m  and n in the given expression

[tex]\frac{1}{3} m -1-\frac{1}{2} n[/tex]

[tex]\frac{1}{3}(21) -1-\frac{1}{2}(12)[/tex]

[tex]\frac{21}{3} -1-\frac{12}{2}[/tex]

[tex]7-1-6= 0[/tex]

So the value of given expression is 0 when we plug in the values of m  and n
