Пошаговое объяснение:

(3- \frac{15}{28} · 1 \frac{1}{6} ) · 2 \frac{2}{19}  = 5

по действиям:

1) \frac{15}{28} · 1 \frac{1}{6} = \frac{15}{28} · \frac{7}{6} = \frac{5}{8}

2) 3 - \frac{5}{8} = 2 \frac{8}{8} - \frac{5}{8} = 2 \frac{3}{8}

3) 2 \frac{3}{8} * 2 \frac{2}{19} = \frac{19}{8} * \frac{40}{19} = 5
