$x= \frac{1}{8} *y$
y известен по очереди подставляем:
1.
$y=0.8= \frac{8}{10} =\ \textgreater \ x= \frac{1}{8} * \frac{8}{10} = \frac{1}{10} =0.1$
2.
$y=2 \frac{2}{3} = \frac{8}{3} =\ \textgreater \ x= \frac{1}{8}* \frac{8}{3} = \frac{1}{3}$
3.
$y=2.4= \frac{24}{10} =\ \textgreater \ x= \frac{1}{8} * \frac{24}{10} = \frac{3}{10} =0.3$
4.
$y=3.2= \frac{32}{10} =\ \textgreater \ x= \frac{1}{8} * \frac{32}{10} = \frac{4}{10} =0.4$
