Answer 2

It looks like you've provided a series of equations with some fractions, and it seems you might be looking for solutions to these equations. Let's solve them one by one:

1. $x \cdot 0.4 = -1$ To solve for $x$, you need to divide both sides of the equation by 0.4: $x = \frac{-1}{0.4} = -2.5$

2. $x \cdot 0.25 = -\frac{4}{5}$ To solve for $x$, divide both sides by 0.25: $x = \frac{-\frac{4}{5}}{0.25} = -\frac{4}{5} \cdot \frac{1}{0.25} = -\frac{16}{5}$

3. $x \cdot \frac{9}{13} = -2$ Divide both sides by $\frac{9}{13}$: $x = -2 \cdot \frac{13}{9} = -\frac{26}{9}$

4. $x \cdot \frac{1}{610}$ (assuming there's a missing equal sign) This equation doesn't have a value on the right side or an equal sign, so it's unclear what the equation is supposed to represent.

Please double-check the formatting and content of the equations, and if you need further assistance, feel free to provide more context or clarification.
