Question

Помогите пожалуйста решить!

Answer 1

$- 2 + 1 \frac{7}{12} = - 1 \frac{12}{12} + 1 \frac{7}{12} = - \frac{5}{12} \\ \frac{3}{8} - \frac{1}{6} = \frac{9 - 4}{24} = \frac{5}{24} \\ - \frac{5}{12} \div \frac{5}{24} = - \frac{5}{12} \times \frac{24}{5} = - 2 \\ - 2 \times 3 \frac{1}{4} = - 2 \times \frac{13}{4} = - \frac{2 \times 13}{4} = - \frac{13}{2} = - 6 \frac{1}{2}$
