\(\frac{7}{11}.\left(\frac{5}{2}-\frac{2}{3}\right)\)
\(=\frac{7}{11}.\left(\frac{15}{6}-\frac{4}{6}\right)\)
\(=\frac{7}{11}.\frac{11}{6}\)
\(=\frac{7}{6}\)
\(\frac{7}{11}\cdot\left(\frac{5}{2}-\frac{2}{3}\right)=\frac{7}{11}.\frac{11}{6}=\frac{7}{6}\)
Chúc bạn học giỏi nha!!!
cau nay de ma =7/6 nhe
chuc ban hoc tot
