Answer 1

$\frac{3}{27x} \\ 27x = 2 \times 100 + 7 \times 1 + x \times 1 = 207 + x \\ x = 3 \: si \: 8 \\ \frac{3}{273} . \frac{3}{278}$

,

$\frac{x5}{7y} = \\ x5 = x \times 10 + 5 \times 1 = 10x + 5 \\ x = (1.4.7) \\ \\ 7y = 7 \times 10 + y \times 1 = 70 + y \\ y = (0.5) \\ \\ \frac{15}{70} . \frac{15}{75} . \frac{45}{70} . \frac{45}{75} . \frac{75}{70} . \frac{75}{75}$
