14/28=1/2
25/50 = 1/2
48/30= 8/5
20/30 = 2/3
Ta có:\(\frac{14}{28}=\frac{14:14}{28:14}=\frac{1}{2}\)
\(\frac{25}{50}=\frac{25:25}{50:25}=\frac{1}{2}\)
\(\frac{48}{30}=\frac{48:6}{30:6}=\frac{8}{5}\)
\(\frac{20}{30}=\frac{20:10}{30:10}=\frac{2}{3}\)
14/28 = 1/2
25/50 = 1/2
48/30 = 8/5
20/30 = 2/3 tink nha
14/28 = 1/2 48/30 = 8/5
25/50 = 1/2 81/54 = 3/2
