(2,06 * 1/60-14,84: 70/60)* 1/6- 0,084* 1/12

(2,06 * 1/60-14,84: 70/60)* 1/6- 0,084* 1/12 = -2\frac{1931}{18000}

2,06 = 2,06*100 = 206/100

14,84 = $14\frac{84}{100}$

0,084 = 0,084*1000 = 84/1000

1) $\frac{206}{100} * \frac{1}{60} = \frac{103}{3000}$

2) $\frac{1484}{100} : \frac{70}{60} = \frac{1484}{100} * \frac{60}{70} = \frac{636}{50}$

3) $\frac{103}{3000} - \frac{636}{50} = \frac{103}{3000} - \frac{38160}{3000} = -\frac{38057}{3000}$

НОЗ: 3000.

4) $-\frac{38057}{3000} * \frac{1}{6} = -\frac{38057}{18000}$

5) $\frac{84}{1000} * \frac{1}{12} = \frac{7}{1000}$

6) $-\frac{38057}{18000} - \frac{7}{1000} = -\frac{38057}{18000} - \frac{126}{18000} = -\frac{37931}{18000} = -2\frac{1931}{18000}$
