Find the module and argument of the complex number

Please find the argument and module of $\frac {2-i}{-\sqrt{3}-2i}$ ?

I have tried This is correct or wrong

1. $\frac {2-i}{-\sqrt{3}-2i}$

2. $\frac {({2-i)}× {(-\sqrt{3}+2i)}}{ {(-\sqrt{3}-2i)}× {(-\sqrt{3}+2i)}}$

3. $\frac {(-2\sqrt{3}+2)+(4+\sqrt{3})i}{3+4}$

4. $\frac{(-2\sqrt{3}+2)}{7}+\frac {(4+\sqrt{3})i}{7}$
