(-3,4+7)*(-1 7/18)

To find the product of these two numbers, we first need to convert the mixed number to an improper fraction.

\((-3, 4 + 7) = (-3, 11) = -3 + 11 = 8\)

Now we can multiply:

\((-3, 11) \times (-1 \frac{7}{18}) = 8 \times (-\frac{65}{18})\)

Now, multiply 8 by -65/18 to get the final result.

\(8 \times (-\frac{65}{18}) = -\frac{520}{18} = -\frac{260}{9}\)

Therefore, the product of \((-3, 4 + 7)\) and \((-1 \frac{7}{18}) is \(-\frac{260}{9}\).
