Answer 1

$0.25 \times 0.2 \times 50 \times ( - 0.4) \times 0.2 {}^{2} \times 50 {}^{2} = - \frac{1}{4} \times \frac{1}{5} \times 50 \times \frac{2}{5} \times ( \frac{1}{5} ) {}^{2} \times 50 {}^{2} = - \frac{1}{2} \times 10 \times \frac{1}{5} \times \frac{1}{25} \times 50 {}^{2} = - 5 \times \frac{1}{5} \times \frac{1}{25} \times 50 {}^{2} = - \frac{1}{25} \times 50 {}^{2} = \frac{ - 50 {}^{2} }{25} = \frac{ - 2500}{25} = - 100$
