помогите пожалуйста!

Answer 1

Ответ:

$\frac{3}{4} - ( -1 \frac{1}{2} ) + ( - \frac{5}{6} ) - ( \frac{3}{8} ) - 4 \frac{2}{3} = \frac{18}{24} + \frac{36}{24} - \frac{20}{24} - \frac{9}{24} - \frac{112}{24} = \frac{(18 + 36) - (20 + 9 + 112)}{24} = \frac{54 - 141}{24} = - \frac{87}{24} = - 3 \frac{5}{8} = - 3 \frac{625}{1000} = - 3.625$
