Answer 1

9 2/3 * 1, 2 + 2 2/3 * 1, 2 - 2 1/3 * 1, 2 = 12

Answer 2

Ответ: 12

$9 \frac{2}{3} \times 1.2 + 2 \frac{2}{3} \times 1.2 - 2 \frac{1}{3} \times 1.2 = \frac{29}{3} \times \frac{12}{10} + \frac{8}{3} \times \frac{12}{10} - \frac{7}{3} \times \frac{12}{10} = \frac{116}{10} + \frac{32}{10} - \frac{28}{10} = \frac{120}{10} = 12$
