ПЖ СРОЧНО!!!!!®™​

Answer 1

$\frac{9}{10} - (\frac{3}{4} - \frac{3}{5}) + \frac{5}{8} = 1,375$

1) $\frac{3}{4} - \frac{3}{5} = \frac{15}{20} - \frac{12}{20} = \frac{3}{20}$

2) $\frac{9}{10} - \frac{3}{20} = \frac{18}{20} - \frac{3}{20} = \frac{15}{20}$

3)  $\frac{15}{20} + \frac{5}{8} = \frac{30}{40} + \frac{25}{40} = \frac{55}{40} = 1,375$
