$$\frac{2}{15}+4\frac{2}{7} \cdot \frac{2}{25} = \frac{2}{15} + \frac{30}{7} \cdot \frac{2}{25} = \frac{2}{15} + \frac{60}{175} = \frac{2}{15} + \frac{12}{35} = \frac{2 \cdot 7}{15 \cdot 7} + \frac{12 \cdot 3}{35 \cdot 3} = \frac{14}{105} + \frac{36}{105} = \frac{14+36}{105} = \frac{50}{105} = \frac{10}{21}$$
