Answer 1

Step-by-step explanation:

$\sqrt{ \frac{9}{100} \times \frac{9}{10} \times x } = \frac{9}{100} \times \frac{9}{10} \times \sqrt{y}$

$\frac{9}{10} \sqrt{ \frac{x}{10} } = \frac{81}{1000} \times \sqrt{y}$

$\sqrt{ \frac{x}{10y} } = \frac{9}{100}$

$\frac{x}{10y} = \frac{9}{100} \times \frac{9}{100}$

$\frac{x}{y} = \frac{81}{1000}$
