Answer 2

    
$\frac{1}{4};\; \frac{1}{9};\; \frac{1}{16};\; \frac{1}{25};\; \frac{1}{36};\; \frac{1}{49};\; \frac{1}{64};\; \frac{1}{81} \\ \\ \frac{4}{9};\; \frac{4}{16};\; \frac{4}{25};\; \frac{4}{36};\; \frac{4}{49};\; \frac{4}{64};\; \frac{4}{81} \\ \\ \frac{9}{16};\; \frac{9}{25};\; \frac{9}{36};\; \frac{9}{49};\; \frac{9}{64};\; \frac{9}{81} \\ \\ \frac{16}{25};\; \frac{16}{36};\; \frac{16}{49};\; \frac{16}{64};\; \frac{16}{81} \\ \\ \frac{25}{36};\; \frac{25}{49};\; \frac{25}{64};\; \frac{25}{81}$

$\frac{36}{49};\; \frac{36}{64};\; \frac{36}{81} \\ \\ \frac{49}{64};\; \frac{49}{81} \\ \\ \frac{54}{81}$
