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
