Answer 1

1.

$\displaystyle \frac{50}{72} = \frac{ {x}^{2} }{ {9}^{2} }$

х=7,5

$\displaystyle \: k = \frac{7.5}{9} = \frac{5}{6}$

2.

$\displaystyle \frac{12}{27} = \frac{ {3}^{2} }{ {x}^{2} }$

х=4,5

$\displaystyle k = \frac{3}{4.5} = \frac{2}{3}$

4.

$\displaystyle \frac{32}{8} = \frac{ {9}^{2} }{ {x}^{2} }$

х=4,5

$\displaystyle \: k = \frac{ 9 }{4.5} = 2$
