Answer 1

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