Question

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

Answer 1

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

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

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

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