Question

 \(\left(3\frac{1}{3}+2,5\right):\left(3\frac{1}{6}-4\frac{1}{5}\right)-\frac{11}{31}\)

Answer 1

\(\left(3\frac{1}{3}+2,5\right):\left(3\frac{1}{6}-4\frac{1}{5}\right)-\frac{11}{31}\)

= \(\left(\frac{10}{3}+\frac{5}{2}\right):\left(\frac{19}{6}-\frac{21}{5}\right)-\frac{11}{31}\)

= \(\frac{35}{6}:\frac{-31}{30}-\frac{11}{31}\)

= \(\frac{175}{-31}\)- \(\frac{11}{31}\)

= -6

Nếu mình đúng thì các bạn k mình nhé

Answer 2

là bằng -6 nhé

Answer 3

\(\left(3\frac{1}{3}+2.5\right):\left(3\frac{1}{6}-4\frac{1}{5}\right)-\frac{11}{31}\)

\(=\left(\frac{10}{3}+\frac{5}{2}\right):\left(\frac{19}{6}-\frac{21}{5}\right)-\frac{1}{3}\)

\(=\left(\frac{20}{6}+\frac{15}{6}\right):\left(\frac{95}{30}-\frac{126}{30}\right)-\frac{1}{3}\)

\(=\frac{35}{6}:\frac{-31}{30}-\frac{1}{3}\)

\(=-\frac{175}{31}-\frac{1}{3}\)

\(=-\frac{525}{93}-\frac{31}{93}\)

\(=-\frac{556}{93}\)
