The question seems to be asking for the solution set of a mathematical problem involving the numbers -4, -1.6, and 3. However, without a specific equation or inequality, it's unclear what the problem is. Assuming we need to find the sum, product, and division of these numbers, we can proceed with these calculations.
- Calculate the sum of the numbers.
- Calculate the product of the numbers.
- Calculate the division of the first number by the second and the second by the third.
To find the sum of the numbers \(-4\), \(-1.6\), and \(3\), we add them together:
\[
-4 + (-1.6) + 3 = -2.6
\]
To find the product of the numbers \(-4\), \(-1.6\), and \(3\), we multiply them:
\[
-4 \times (-1.6) \times 3 = 19.20
\]
To find the division of the first number by the second, we divide \(-4\) by \(-1.6\):
\[
\frac{-4}{-1.6} = 2.5
\]
To find the division of the second number by the third, we divide \(-1.6\) by \(3\):
\[
\frac{-1.6}{3} = -0.5333
\]
- Sum: \(\boxed{-2.6}\)
- Product: \(\boxed{19.20}\)
- Division of the first by the second: \(\boxed{2.5}\)
- Division of the second by the third: \(\boxed{-0.5333}\)
