Question

Обчислить зручним способом 2 3/4-(1 1/2)+(-5/6)-(- 3/8)-4 2/3=

Answer 1

$2\frac{3}{4} - (-1\frac{1}{2}) + (-\frac{5}{6}) - (-\frac{3}{8}) - 4\frac{2}{3} =$

$2\frac{3}{4} + 1\frac{1}{2} - \frac{5}{6} + \frac{3}{8} - 4\frac{2}{3} =$

НОД (4;2;6;8;3) = 24

$2\frac{18}{24} + 1\frac{12}{24} - \frac{20}{24} + \frac{9}{24} - 4\frac{16}{24} =$

$4\frac{6}{24} - 1\frac{5}{24} - 4\frac{16}{24} =$

$(-\frac{10}{24} )-1\frac{5}{24} = -1\frac{15}{24}$

Ответ: $-1\frac{15}{24}$.

Удачи!!!
