22.4+1,25-27. 78

$$2 \frac{2}{7} \cdot 4 \frac{7}{8} + 1,25 \cdot 2 \frac{2}{7} = \frac{2 \cdot 7 + 2}{7} \cdot \frac{4 \cdot 8 + 7}{8} + \frac{125}{100} \cdot \frac{2 \cdot 7 + 2}{7} = \frac{14 + 2}{7} \cdot \frac{32 + 7}{8} + \frac{5}{4} \cdot \frac{14+2}{7} = \frac{16}{7} \cdot \frac{39}{8} + \frac{5}{4} \cdot \frac{16}{7} = \frac{2 \cdot 39}{7} + \frac{5 \cdot 4}{7} = \frac{78}{7} + \frac{20}{7} = \frac{78+20}{7} = \frac{98}{7} = 14 $$
