1) Ta có : \(\frac{49}{28}=\frac{49:7}{28:7}=\frac{7}{4}\)
\(\frac{85}{51}=\frac{85:17}{51:17}=\frac{5}{3}\)
\(\frac{64}{96}=\frac{64:32}{96:32}=\frac{2}{3}\)
\(\frac{1212}{3030}=\frac{1212:606}{3030:606}=\frac{2}{5}\)
\(\frac{32032}{48048}=\frac{32032:16016}{48048:16016}=\frac{2}{3}\)
\(\frac{1339}{1442}=\frac{1339:103}{1442:103}=\frac{13}{14}\)
