Question

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

Answer 1

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