Answer 1

$frac{2}{4} = frac{2}{2*2} = frac{1}{2} ; \ frac{5}{15} = frac{5}{5*3}= frac{1}{3} ; \ frac{25}{125} = frac{1}{5} ; frac{16}{20}= frac{4}{5}; frac{8}{16}= frac{1}{2}; frac{10}{100}= frac{1}{10}; frac{100}{1000}= frac{1}{10} ; frac{81}{90}= frac{9}{10}; frac{11}{121}= frac{1}{11}; \ frac{12}{144} = frac{1}{12}; frac{15}{75}= frac{1}{5}$
