for any fraction, a/b, the decimal form of it is simply the quotient of a ÷ b.

let's firstly convert the mixed fraction to improper fraction, then divide.


[tex]\bf \stackrel{mixed}{-2\frac{5}{22}}\implies -\cfrac{2\cdot 22+5}{22}\implies \stackrel{improper}{-\cfrac{47}{22}}\implies -47\div 22\implies \stackrel{\stackrel{decimal}{\downarrow }}{-2.1\overline{36}}[/tex]
