Answer 3

It seems like you've provided a mathematical expression that needs to be evaluated. Let's break it down step by step:

1. $8 \times 7 + (2 \times 9)$ $= 56 + 18$ $= 74$

2. $3 - 81$ This results in -78.

3. $16 - 7$ $= 9$

4. Putting it all together: $\frac{74}{-78} \div 9$ $= -0.94871794872$

So, the value of the expression $8 \times 7 + (2 \times 9) : 3 - 81 : (16 - 7)$ is approximately -0.9487.
