а) $$x : 9 = 6\frac{5}{36}$$
$$x = 6\frac{5}{36} \cdot 9$$
$$x = \frac{221}{36} \cdot 9$$
$$x = \frac{221 \cdot 9}{36}$$
$$x = \frac{221}{4} = 55\frac{1}{4} = 55,25$$
б) $$y : 7 = 5\frac{9}{28}$$
$$y = 5\frac{9}{28} \cdot 7$$
$$y = \frac{149}{28} \cdot 7$$
$$y = \frac{149 \cdot 7}{28}$$
$$y = \frac{149}{4} = 37\frac{1}{4} = 37,25$$
