I used a calculator

Answer 2

Method 1:

$4\dfrac{2}{5}=4\dfrac{2\cdot2}{5\cdot2}=4\dfrac{4}{10}=4.4\\\\4\dfrac{2}{5}:16.5=4.4:16.5=44:165=0.2666...=0.2(6)=0.2\overline{6}$

Method 2:

$16.5=\dfrac{165}{10}=\dfrac{165:5}{10:5}=\dfrac{33}{2}\\\\4\dfrac{2}{5}=\dfrac{4\cdot5+2}{5}=\dfrac{22}{5}\\\\4\dfrac{2}{5}:16.5=\dfrac{22}{5}:\dfrac{33}{2}=\dfrac{22}{5}\cdot\dfrac{2}{33}=\dfrac{2}{5}\cdot\dfrac{2}{3}=\dfrac{4}{15}$
