Решение:
$$p - \frac{3}{11}p + 2\frac{15}{22}p = \frac{11}{11}p - \frac{3}{11}p + \frac{59}{22}p = \frac{8}{11}p + \frac{59}{22}p = \frac{16}{22}p + \frac{59}{22}p = \frac{75}{22}p$$
При $$p = 1\frac{19}{25} = \frac{44}{25}$$
$$\frac{75}{22} \cdot \frac{44}{25} = \frac{75 \cdot 44}{22 \cdot 25} = \frac{3 \cdot 2}{1 \cdot 1} = 6$$
