$- 10.25$

Explanation:

Add the whole numbers with whole numbers, and decimals with decimals.

You could seperate it by decimals and whole numbers if that helps.

So find what $- 5 + \left(- 4\right)$is, which is the same as $- 5 - 4$. It should be $- 9$.

Now lets do the decimals. Find out what $\left(- 0.8\right) + \left(- 0.45\right)$ is. This is the same as $\left(- 0.8\right) - 0.45$ This equals to $- 1.25$

Add it together: $- 9 + \left(- 1.25\right) \mathmr{and} - 9 - 1.25 = - 10.25$

Easiest way to solve this is to input it in your calculator.
