Tính giá trị biểu thức: M= (0,4-2/9+2/11)/(1,4-7/9-7/11)-(1/3-0,25+1/5)/(7/6-0,875+0,7):2012/2013
Tính M=\(\left(\dfrac{0,4-\dfrac{2}{9}+\dfrac{2}{11}}{1,4-\dfrac{7}{9}+\dfrac{7}{11}}-\dfrac{\dfrac{1}{3}-0,25+\dfrac{1}{5}}{1\dfrac{1}{6}-0,875+0,7}\right):\dfrac{2021}{2022}\)

tính:
\(Q=2002:\left[\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}.\frac{-1\frac{1}{6}+0,875-0,7}{\frac{1}{3}-0,25+\frac{1}{5}}\right]\)
tính: \(Q=\left[\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}.\frac{-1\frac{1}{6}+0,875-0,7}{\frac{1}{3}-0,25+\frac{1}{5}}\right]\)
Tính :
M=\((\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}-\frac{\frac{1}{3}-0,25+\frac{1}{5}}{1\frac{1}{6}-0,875+0,7})\div\frac{2014}{2015}\)
\(M=\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}-\frac{\frac{1}{3}-0,25+\frac{1}{5}}{1\frac{1}{6}-0,875+0,7}:\frac{2014}{2015}\)
