-0.22

here is your answer

Answer 2

Step-by-step explanation:

$\frac{0.4 \times 0.04 \times 0.005}{0.1 \times 10 \times 0.001} - \frac{1}{2} + \frac{1}{5} \\ \frac{4 \times 4 \times 5}{1 \times 10 \times1} \times \frac{10 \times 1000}{10 \times 100 \times 1000} - \frac{1}{2} + \frac{1}{5} \\ \frac{80}{10} \times \frac{10000}{1000000} - \frac{1}{2} + \frac{1}{5} \\ \frac{800000 }{10000000} - \frac{1}{2} + \frac{1}{5} \\ \frac{8}{100} - \frac{1}{2} + \frac{1}{5} \\ \frac{8}{100} + \frac{1}{5} - \frac{1}{2} \\ \frac{8 + 20}{100} - \frac{1}{2} \\ \frac{28}{100} - \frac{1}{2} \\ \frac{28 - 50}{100} \\ - \frac{ 22}{100} \\ - \frac{11}{50}$
