Tính :
M=\((\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}-\frac{\frac{1}{3}-0,25+\frac{1}{5}}{1\frac{1}{6}-0,875+0,7})\div\frac{2014}{2015}\)
Tính A= \(\left[\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}-\frac{\frac{1}{3}-0,25+\frac{1}{5}}{1\frac{1}{6}-0,875+0,7}\right]:\frac{2014}{2015}\)
So sánh 199110 với 99612
M=\(\hept{\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}-\frac{\frac{1}{3}-0,25+\frac{1}{5}}{1\frac{1}{6}-0,875+0,7}}\)
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 giá trị của biểu thức sau:
\(2014:\left(\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1\frac{2}{5}-\frac{7}{9}+\frac{7}{11}}.\frac{1\frac{1}{6}+0,875-0,7}{\frac{1}{3}+0,25-\frac{1}{5}}\right)\)
1/M=(\(\frac{0,4-\frac{2}{9}+\frac{2}{11}}{1,4-\frac{7}{9}+\frac{7}{11}}-\frac{\frac{1}{3}-0,25+1,5}{1\frac{1}{6}-0,875+0,7}\)) :\(\frac{2012}{2013}\)
