Question

-3/8×(-5/7)×(-18/20)=(-3/8×-5/9)×-18/20 verify ​

Answer 1

Answer:

$\frac{ - 3}{8} \times ( \frac{ - 5}{7} ) \times ( \frac{ - 18}{20} ) = (\frac{ - 3}{8} \times - \frac{5}{9} ) \times \frac{ - 18}{20} \\ = \frac{15}{56} \times \frac{ - 18}{20} = \frac{5}{24} \times \frac{ - 18}{20} \\ \frac{3}{28} \times \frac{ - 9}{4} = \frac{1}{4} \times \frac{ - 3}{4} \\ \frac{ - 27}{104} = - \frac{ - 3}{16} \\ therefore,\frac{ - 27}{104} is \: not \: equal \: to \: - \frac{ - 3}{16}$
