Answer 1

Answer:

The expression is equal to zero for the given values

Step-by-step explanation:

The correct question is

Evaluate start fraction, 1, divided by, 3, end fraction, m, minus, 1, minus, start fraction, 1, divided by, 2, end fraction, n   when m=21 and n=12

we have the expression

 $\frac{1}{3}m-1-\frac{1}{2}n$

we know that

To evaluate the expression substitute the given values of m and n

For m=21 and n=12

$\frac{1}{3}(21)-1-\frac{1}{2}(12)$

solve the multiplications

$7-1-6$

solve the subtraction

$7-7\\0$

therefore

The expression is equal to zero for the given values
