Answer 2

Let the number to be found be x.

$\tt \frac{ - 9}{ \: \: \: \: 20} \div x = \frac{ - 3}{ \: \: \: \: 2} \\ \\ \tt \frac{ - 9}{ \: \: \: 20 } \times \frac{1}{x} = \frac{ - 3}{ \: \: \: 2} \\ \\ \tt \frac{ - 9}{20x} = \frac{ - 3}{ \: \: \: \: 2} \\ \\ \tt - 9 \times 2 = - 3 \times 20x \\ \\ \tt - 18 = - 60x \\ \\ \tt \frac{ - 18}{ - 60} = x \\ \\ \tt{ cancelling \: \: by \: \: 3 }\\ \\ \tt \frac{6}{20} = x \\ \\ \tt{cancelling \: \: by \: \: 2} \\ \\ \tt{\boxed{ \frac{3}{10} = x}}$
