Question

1челая 8/9:(1чела 3/4-3челая1/6)•(-9/16​

Answer 1

$1 \frac{8}{9} \div (1 \frac{3}{4} - 3 \frac{1}{6} ) \times \frac{9}{16} = - 0.75 \\ 1 \frac{3}{4} - 3 \frac{1}{6} = 1 \frac{9}{12} - 3 \frac{2}{12} = 1 \frac{9}{12} - 2 \frac{14}{12} = - 1 \frac{5}{12} \\ 1 \frac{8}{9} \div ( - 1 \frac{5}{12} ) = - \frac{17 \times 12}{9 \times 17} = - \frac{4}{3} \\ - \frac{4}{3} \times \frac{9}{16} = - \frac{4 \times 9}{3 \times 16} = - \frac{1 \times 3}{ 1\times 4} = - \frac{3}{4} = - 0.75$
