Answer 1

$\frac{1.8}{(4 \times \frac{2}{5} \times 6 \times \frac{1}{3} - 2 \times \frac{1}{3} \times 4.4) \times \frac{5}{22} } = \frac{1.8}{( \frac{22}{5} \times \frac{19}{3} - \frac{7}{3} \times 4.4) \frac{5}{22} } = \frac{1.8}{( \frac{418}{15} - \frac{30.8}{3}) \times \frac{5}{22} } = \frac{1.8}{ \frac{418 - 154}{15} \times \frac{5}{22} } = \frac{1.8}{ \frac{264}{15} \times \frac{5}{22} } = \frac{1.8}{4} = 0.45$
