a) 15 * (-7); б) – 14 * (-17); в) - 0,9 * 4,1; г) - 3/16 *(-3 5/9)

Решаем:

1. a) 15 * (-7) = -105;
2. б) – 14 * (-17) = 238;
3. в) - 0,9 * 4,1 = -3,69;
4. г) – \(\frac{3}{16}\) * (-\(\frac{32}{9}\)) = \(\frac{3}{16}\) * \(\frac{32}{9}\) = \(\frac{1}{1}\) * \(\frac{2}{3}\) = \(\frac{2}{3}\).

Ответ: a) -105; б) 238; в) -3,69; г) \(\frac{2}{3}\).
