$80.8$ $80.8$

Explanation:

$16.16 \div 0.2 = 16.16 \div (\frac{2}{10}) = 16.16 \cdot (\frac{10}{2}) = 16.16 \cdot 5 = 80.80$ $16.16 -: 0.2 = 16.16 -: (2/10) = 16.16 * (10/2) = 16.16 * 5 = 80.80$

Dividing by a number is the same as multiplying by its reciprocal.

In our example, instead of dividing by $\frac{2}{10}$ $2/10$ we can multiply by $\frac{10}{2}$ $10/2$ .
