\(\frac{150}{250}\)=\(\frac{3}{5}\)
\(\frac{1000}{2000}\)=\(\frac{1}{2}\)
\(\frac{150}{250}=\frac{150\div50}{250\div50}=\frac{3}{5}\)
em muốn nhanh thì lần sau em tách câu hỏi ra chứ đừng hỏi nhiều trong một câu em nhé
\(\dfrac{12}{48}\) = \(\dfrac{12:12}{48:12}=\) \(\dfrac{1}{2}\) \(\dfrac{49}{140}\) = \(\dfrac{49:7}{140:7}\) = \(\dfrac{7}{20}\)
\(\dfrac{125}{1000}\) = \(\dfrac{125:125}{1000:125}\) = \(\dfrac{1}{8}\) \(\dfrac{352}{253}\) = \(\dfrac{352:11}{253:11}\)= \(\dfrac{32}{23}\)
