\(M=\left[\left(\frac{2}{193}-\frac{3}{386}\right).\frac{193}{17}+\frac{33}{34}\right]:\left[\left(\frac{7}{2001}+\frac{11}{4002}\right).\frac{2001}{25}+\frac{9}{2}\right]\)
tính
M=\(\frac{\left[\left(\frac{2}{193}-\frac{3}{386}\right)\cdot\frac{193}{17}+\frac{33}{34}\right]}{\left[\left(\frac{7}{2001}+\frac{11}{4002}\right)\cdot\frac{2001}{25}+\frac{9}{2}\right]}\)
M = [(\(\frac{3}{4}\)+ \(\frac{3}{386}\))] . \(\frac{193}{17}\). \(\frac{33}{34}\)] : [(\(\frac{7}{2011}\)+ \(\frac{11}{4002}\)) . \(\frac{2001}{25}+\frac{9}{2}\)]
Bài 1: Tìm 2 số hữu tỉ x và y sao cho x + y = xy = x : y (y khác 0)
Bài 2: Tính:
M = [(2/193 - 3/386) . 193/17 + 33/34] : [( 7/2001 + 11/4002) . 2001/25 + 9/2]
Bài 3: Cho A = [0,8 . 7 + (0,82] . (1,25 . 7 - 4/5 . 1,25) + 31,64
B \(\left(1,09-0,29\right).\frac{5}{4}\)trên \(\left(18,9-16,65\right).\frac{8}{9}\)
Hỏi A gấp mấy lần B?
Tính
\(\left(\left(\frac{2}{193}-\frac{3}{386}\right)-\frac{193}{17}+\frac{33}{34}\right):\left(\left(\frac{7}{1931}+\frac{11}{3862}\right).\frac{1931}{25}+\frac{9}{2}\right)\)
tính:
\(A=\left[\left(\frac{2}{193}-\frac{3}{386}\right).\frac{193}{17}+\frac{33}{34}\right]:\left[\left(\frac{7}{1931}+\frac{11}{3862}\right).\frac{1931}{25}+\frac{9}{2}\right]\)
Tính: [(7/2001 + 11/4002) . 2001/25 + 9/2]:[(2/193 - 3/386) . 193/17 + 33/34]
Tính hợp lý : ((2/193-3/386).193/17+33/34):((7/2001+11/4002)201/25+9/2)
Tính: [(2/193 - 3/386) . 193/17 + 33/34] : [(7/2001 + 11/4002) . 2001/25 + 9/2]
