МАТЕМАТИКА: 201-(146,7:13,4+1,6)*2,8 ДАМ 20 БАЛЛОВ СРОЧНО!!!

Answer 1

$201 - (146.7 \div 13.4 + 1.6) \times 2.8 = 201 - ( \frac{1467}{10} \div \frac{67}{5} + \frac{8}{5} ) \times \frac{14}{5} = 201 - ( \frac{1467}{5} \times \frac{1}{67} + \frac{8}{5} ) \times \frac{14}{5} = 201 - (\frac{1467}{134} + \frac{8}{5} ) \times \frac{14}{5} = 201 - \frac{847}{335} \times \frac{7}{5} = 201 - \frac{58849}{1675} = \frac{277826}{1675} = 165 \frac{1451}{1675}$
