Question

(5 5/28- 5 1/3*1,25-1 16/21):(-1,5)

Answer 1

$(5 frac{5}{28} - 5 frac{1}{3} times 1.25 - 1 frac{16}{21} ) div ( - 1.5) = ( frac{145}{28} - frac{16}{3} times frac{5}{4} - frac{37}{21} ) div ( - frac{3}{2} ) = ( frac{145}{28} - frac{80}{12} - frac{37}{21} ) div ( - frac{3}{2} ) = ( frac{435}{84} - frac{560}{84} - frac{148}{84} ) times ( - frac{2}{3} ) = - frac{273}{84} times ( - frac{2}{3} ) = frac{91 times 1}{42 times 1} = frac{91}{42} = 2 frac{7}{42} = 2 frac{1}{6}$
