Решение:
- 1) \(-1 - (-15) = -1 + 15 = 14\)
- 2) \(-1,95 - 8,68 = -10,63\)
- 3) \(-7 - (-4) + 3 = -7 + 4 + 3 = 0\)
- 4) \(-2,16 : \frac{3}{50} = -2,16 \cdot \frac{50}{3} = -0,72 \cdot 50 = -36\)
- 5) \(1 \frac{1}{8} - 3 \frac{5}{6} = \frac{9}{8} - \frac{23}{6} = \frac{27}{24} - \frac{92}{24} = \frac{-65}{24} = -2 \frac{17}{24}\)
Ответ: 1) 14; 2) -10,63; 3) 0; 4) -36; 5) -2 17/24
