Answer:

The value of the expression at given values of m and n is 8.

Explanation:

We have been given that


0.1m+8-12n\\\\m=30,n=(1)/(4)

On substituting the values of m and n in the given expression


0.1\cdot30+8-12\cdot(1)/(4)\\\\\mathrm{Multiply\:the\:numbers:}\:0.1\cdot \:30=3\\\\3+8-(1)/(4)\\\\\text{On simplifying, we get}\\\\3+8-3\\\\\=8

Thus, the value of the expression at given values of m and n is 8.
