\(\frac{49}{28}=\frac{49:7}{28:7}=\frac{7}{4},\frac{24}{56}=\frac{24:8}{56:8}=\frac{3}{7}\) 

\(\frac{12}{21}=\frac{12:3}{12:3}=\frac{4}{7},\frac{25}{50}=\frac{25:25}{50:25}=\frac{1}{2}\)

\(\frac{45}{27}=\frac{45:9}{27:9}=\frac{5}{3},\frac{22}{121}=\frac{22:11}{121:11}=\frac{2}{11}\)

\(\frac{196}{28}=\frac{196:28}{28:28}=\frac{7}{1},\frac{26}{169}=\frac{26:13}{169:13}=\frac{2}{13}\)

\(\frac{221}{187}=\frac{221:17}{187:17}=\frac{13}{11}\)
