\(\frac{2011.2013-2011.2012}{2012.2011+2011.2013}\)
\(=\frac{2011.\left(2013-2012\right)}{2011.\left(2012+2013\right)}\)
\(=\frac{2011.1}{2011.4025}\)
\(=\frac{1}{4025}\)
bài này là bài Tính nha mọi người giải rõ ra giúp mik nha
\(\frac{2011x2013-2012x2011}{2012x2011+2011x2013}\)
\(=\frac{2011x\left(2013-2012\right)}{2011x\left(2012+2013\right)}\)
\(=\frac{2011x1}{2011x4025}\)
\(=\frac{1}{4025}\)
\(2011\times2013-2012\times2011=2011\)
\(2012\times2011+2011\times2013=8094275\)

2011 x 2013 - 2012 x 2011
= 4048143 - 4046132
= 2011
2012 x 2011 + 2011 x 2013
= 4046132 + 4048143
= 8094275
