\(\left(5-\frac{23}{7}\right)×\frac{63}{24}+\frac{11}{9}:\frac{2}{3}\)
\(=\frac{12}{7}×\frac{63}{24}+\frac{11}{9}:\frac{2}{3}\)
\(=\frac{9}{2}+\frac{11}{9}:\frac{2}{3}\)
\(=\frac{9}{2}+\frac{11}{6}\)
\(=\frac{19}{3}\)
Bằng 19/3 nha

Bài làm :
Ta có :
\(\left(5-\frac{23}{7}\right)×\frac{63}{24}+\frac{11}{9}\div\frac{2}{3}\)
\(=\frac{12}{7}×\frac{63}{24}+\frac{11}{9}\div\frac{2}{3}\)
\(=\frac{9}{2}+\frac{11}{6}\)
\(=\frac{19}{3}\)
