Answer 1

Answer:

$25\% \times 30\% \times 10\% \times 90\% \\ \frac{25}{100} \times \frac{30}{100} \times \frac{10}{100} \times \frac{90}{100} \\ = \frac{1}{4} \times \frac{3}{10} \times \frac{1}{10} \times \frac{9}{10} \\ = \frac{27}{4000} \\ = (\frac{27 \times 100}{4000} )\% \\ = \frac{27}{40} \%$
