Answer 1

$\frac{12}{15} = \frac{4}{5} = 0.8 \\ \frac{21}{35} = \frac{3}{5} = 0.6 \\ \frac{12}{30} = \frac{2}{5} = 0.4 \\ \frac{45}{50} = \frac{9}{10} = 0.9 \\ \frac{18}{90} = \frac{1}{5} = 0.2 \\ \frac{56}{80} = \frac{7}{10} = 0.7 \\ \frac{9}{12} = \frac{3}{4} = 0.75 \\ \frac{21}{60} = \frac{7}{20} = 0.35$
