Question

помогите пожалуйста ​

Answer 1

а)

$- 5 \times \frac{3}{5} + \frac{3}{5} \times ( - 11) = \frac{3}{5} ( - 5 - 11) = \\ \\ = \frac{3}{5} \times ( - 16) = - \frac{48}{5} = - 9 \frac{3}{5} = \\ = - 9.6$

б)

$- 2.9 \times 2 \times ( - 0.5) \times 4 = - 2.9 \times 2 \times ( - 2) = - 2.9 \times ( - 4) = 11.6$
