\(\frac{2}{3}+\frac{1}{3}.\left(\frac{-4}{9}+\frac{3}{6}\right):\frac{7}{12}\)
\(=\frac{2}{3}+\frac{1}{3}.\frac{1}{18}:\frac{7}{12}\)
\(=\frac{2}{3}+\frac{1}{54}:\frac{7}{12}\)
\(=\frac{2}{3}+\frac{2}{63}\)
\(=\frac{44}{63}\)

#)Giải :
= 2/3 + 1/3 . 1/18 : 7/12
= 2/3 + 1/54 : 7/12
= 2/3 + 2/63
= 44/63
#~Will~be~Pens~#
2/3+1/3.(-4/9+3/6):7/12
=2/3+1/3.1/18.12/7
=2/3+1/54.12/7
=2/3+2/63
=44/63
chúc bạn học tốt

Trả lời :
\(\frac{2}{3}\) \(+\) \(\frac{1}{3}\)\(.\) \(\left(\frac{-4}{9}+\frac{3}{6}\right):\frac{7}{12}\)
\(=\) \(\frac{2}{3}\) \(+\) \(\frac{1}{3}\) \(.\) \(\frac{1}{18}.\frac{12}{7}\)
\(=\) \(\frac{2}{3}\) \(+\) \(\frac{1}{54}..\frac{12}{7}\)
\(=\)\(\frac{2}{3}\) \(+\) \(\frac{2}{63}\)
\(=\) \(\frac{44}{63}\)
