Answer 1

Suppose that the number is x,

Hence,,

$( \frac{4}{5} ) {}^{ - 2} \div x = 125 \\ = > ( \frac{5}{4} ) {}^{2} \div x = 125 \\ = > \frac{25}{16} \div x = 125 \\ = > \frac{25}{16} = 125x \\ = > 125x = \frac{25}{16} \\ = > x = \frac{25}{16 \times 125} \\ = > x = \frac{1}{16 \times 5} \\ = > x = \frac{1}{80} \: ans..$

Hence, the number is 1/80 Ans..

Hope it helps you.. thanks
