Question

1) -3,6/0,9 2) -0,75 : 1 8/17 3) 2236 : (-0,8) . найдите значение выражения.

Answer 1

1)

$\frac{ - 3.6}{0.9} = - \frac{3.6}{1} \div \frac{9}{10} = - \frac{3.6}{1} \times \frac{10}{9} = \\ = - \frac{36}{9} = - 4$

2)

$- 0.75 \div 1 \frac{8}{17} = - \frac{75}{100} \div \frac{25}{17} = \\ = - \frac{75}{100} \times \frac{17}{25} = - \frac{51}{100} = - 0.51$

3)

$2236 \div ( - 0.8) = 2236 \div ( - \frac{8}{10} ) = \\ = 2236 \times ( - \frac{10}{8} ) = - \frac{22360}{8} = - 2759$
