\(M=2\frac{1}{433}\frac{3}{229}-\frac{432}{433}.\frac{1}{229}-\frac{4}{433.229}\)
\(N=3\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.119}-\frac{8}{39}\)
Tính :
a)\(M=2\frac{1}{433}\cdot\frac{3}{229}-\frac{432}{433}\cdot\frac{1}{229}-\frac{4}{433\cdot119}\)
b)\(N=3\frac{1}{117}\cdot\frac{1}{119}-\frac{4}{117}\cdot5\frac{118}{119}-\frac{5}{117\cdot119}-\frac{8}{39}\)
