Tính nhanh:
\(3\frac{1}{417}.\frac{1}{762}-\frac{1}{139}.4\frac{761}{762}-\frac{4}{417.762}+\frac{5}{139}\)
Tính nhanh \(P=3\frac{1}{417}.\frac{1}{762}-\frac{1}{139}.4\frac{761}{762}-\frac{4}{417.762}+\frac{5}{139}\)
Tính A =\(726\frac{1}{417}.\frac{1}{762}-\frac{1}{139}.4\frac{761}{762}-\frac{4}{417.762}+\frac{5}{139}\)
Tính nhanh:(3+1/417)*1/762-1/139*(4+761/762)-4/(417*762)+5/139
Tính tổng : M= 3+1/147. 1/762-1/139.4+761/762 -4/417.762 +5/139
Tính P = 3/1/417.1/762-1/139.4/761/762-4/417.762+5/139
\(3\frac{1}{417}\cdot\frac{1}{762}-\frac{1}{139}\cdot4\frac{761}{762}-\frac{4}{417\cdot762}+\frac{5}{139}\)
\(3\frac{1}{417}\times\frac{1}{762}-\frac{1}{139}\times4\frac{761}{762}-\frac{4}{417\times762}+\frac{5}{139}=?\)
