Answer 1

$\frac{ \sqrt{481 - 27 \times \sqrt{9} } }{x} = \frac{ \sqrt{55 + 5 \times {3}^{2} } }{1 \times \frac{4}{5} \times \sqrt{2.(7)} }$

$\frac{ \sqrt{481 - 27 \times 3} }{x} = \frac{ \sqrt{55 + 45} }{ \frac{4}{5} \times \sqrt{2 \frac{7}{9} } }$

$\frac{ \sqrt{481 - 81} }{x} = \frac{ \sqrt{100} }{ \frac{4}{5} \times \sqrt{ \frac{25}{9} } }$

$\frac{ \sqrt{400} }{x} = \frac{10}{ \frac{4}{5} \times \frac{5}{3} }$

$\frac{20}{x} = \frac{10}{ \frac{20}{15} }$

$\frac{20}{x} = \frac{10}{1} \times \frac{15}{20}$

$\frac{20}{x} = \frac{150}{20}$

$= > x = \frac{20 \times 20}{150}$

$x = \frac{400}{150 } = \frac{8}{3} = 2.(6)$
