Final answer:
When we substitute m=-8, n=-7 into the expression mn/8, we get the result as 7.
Step-by-step explanation:
Let's start by substituting the values of m and n. The given expression is mn/8. If we substitute m = -8 and n = -7, the expression becomes (-8 * -7)/8.
The multiplication of two negative numbers results in a positive number, so -8 * -7 equals 56. Therefore, our expression now becomes 56/8.
Finally, doing the division 56 divided by 8 equals 7. Hence, for m = -8 and n = -7, mn/8 = 7.
