Question

Tính nhanh :

\(\frac{2010\cdot2011+1000}{2012\cdot2010-1010}\)

Answer 1

\(\frac{2010\cdot2011+1000}{2012\cdot2010-1010}\)

= \(\frac{2010\cdot2011+1000}{\left(2011+1\right)\cdot2010-1010}\)

= \(\frac{2010\cdot2011+1000}{2011\cdot2010+2010-1010}\)

= \(\frac{2010\cdot2011+1000}{2011\cdot2010+1000}\)

= 1

Answer 2

\(\frac{2010.2011+1000}{2012.2010-1010}\)

\(=\frac{2010.2011+2010-1010}{2012.2010-1010}\)

\(=\frac{2010.\left(2011+1\right)-1010}{2012.2010-1010}\)

\(=\frac{2010.2012-1010}{2012.2010-1010}\)

\(=1\)

Answer 3

\(\frac{2010\cdot2011+1000}{2012\cdot2010-1010}\)= \(\frac{2010\cdot2011+1000}{2011\cdot2010+2010-1010}\)= \(\frac{2010\cdot2011+1000}{2011\cdot2010+1000}\)= 1
