em muốn nhanh thì lần sau em tách câu hỏi ra chứ đừng hỏi nhiều trong một câu em nhé
\(\dfrac{12}{48}\) = \(\dfrac{12:12}{48:12}=\) \(\dfrac{1}{2}\) \(\dfrac{49}{140}\) = \(\dfrac{49:7}{140:7}\) = \(\dfrac{7}{20}\)

giúp mình nhé! Sao lúc nào mình cần câu trả lời thì chờ mãi ko thấy ai trả lời thế?
a. \(\frac{34}{50}=\frac{2\times17}{2\times25}=\frac{17}{25}\); \(\frac{48}{68}=\frac{4\times12}{4\times17}=\frac{12}{17}\); \(\frac{1313}{2323}=\frac{101\times13}{101\times23}=\frac{13}{23}\); \(\frac{515151}{636363}=\frac{10101\times51}{10101\times63}=\frac{51}{63}\)
b. +) \(\frac{3}{15}=\frac{3}{3\times5}=\frac{1}{5}\); \(\frac{33}{44}=\frac{3\times11}{4\times11}=\frac{3}{4}\); \(\frac{2}{8}=\frac{2}{2\times4}=\frac{1}{4}\)

3/1 3/50 4/3
33/11=3/1=3
75/200=3/8
80/60=4/3
tích mk nhé
