M=m=(7/2012+7/9-1/4):(5/9-3/2012-1/2)
M=\(\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\) tính M
a) tinh M=7/2012+7/9-1/4 / 5/9-3/2012-1/2
1.tính M=\(\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\)
\(M=\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
\(M=\frac{\frac{63}{18108}-\frac{14084}{18108}-\frac{4527}{18108}}{\frac{10060}{18108}-\frac{27}{18108}-\frac{9054}{18108}}\)
\(M=\frac{-18548}{979}\)
Mình tin chắc đề bài sai , số to quá !!!
Tính \(M=\frac{\frac{7}{2012}+\frac{7}{9}+\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
\(\frac{\frac{7}{2012}+\frac{7}{9}+\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}=\left(\frac{7}{2012}+\frac{7}{9}+\frac{1}{4}\right):\left(\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}\right)\)
\(=\frac{9337}{9054}:\frac{97}{18108}=\frac{9337}{9054}.\frac{18108}{97}=\frac{18674}{97}\)
1.tính M=\(\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\)
Tính \(M=\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\)
tính M
M = \(\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
so sánh A và B biết
A = \(\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\)
B = \(\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+...+\frac{1}{17}\)
bài 1 :a) Tính M:\(\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
b) So sánh A và B biết A =\(\frac{2010}{2011}+\frac{2011}{2012}+\frac{2012}{2010}\);;; B =\(\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+....+\frac{1}{17}\)
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
