27/8 - 7/3 + 4/3 - 2
= 27/8 - (7/3 - 4/3) - 2
= 27/8 - 1 - 2
=27/8 - 3
= 3/8
= 27/8-(7/3-4/3)-1
=27/8-1-1
=27/8-2
=11/8

\(\frac{27}{8}\) \(-\)\(\frac{7}{3}\)\(+\)\(\frac{4}{3}\)\(-\)2
=\(\frac{27}{8}\)\(+\)(\(\frac{-7}{3}\)\(+\)\(\frac{4}{3}\)) \(-\)2
= \(\frac{27}{8}\)\(-\)1 \(-\)2
=\(\frac{27}{8}\)\(-\)3
= \(\frac{3}{8}\)
Chúc các anh em hoc tốt !!!
