Answer 1

$4.573 + 2 \frac{2}{7} \times 3 \frac{1}{8} - (2.073 - 1 \frac{5}{7} \times 3 \frac{1}{8} ) = 4.573 + \frac{16}{7} \times \frac{25}{8} - 2.073 + \frac{12}{7} \times \frac{25}{8} = \\ \\ = 4.573 - 2.073 + \frac{16}{7} \times \frac{25}{8} + \frac{12}{7} \times \frac{25}{8} = 2.5 + \frac{25}{8} ( \frac{16}{7} + \frac{12}{7} ) = 2.5 + \frac{25}{8} \times 4 = 2.5 + \frac{25}{2} = 2.5 + 12.5 = 15$
