Question

tính nhanh : 2010 x 125 + 1000 / 126 x 2010 - 1010

Answer 1

\(\frac{2010.125+1000}{126.2010-1010}=\frac{10\left(201.125+100\right)}{10\left(201.126-101\right)}=\frac{201.125-101+201}{2011.126-101}\)

\(=\frac{201.126-101}{201.126-101}=1\)

Answer 2

=2010 x 125 + 2010x 126 + 1000+1010

=2010 x 125 + 2010 x 126 + 2010

=2010 x ( 125 + 126 +1 )

=2010 x 252

=506520

Answer 3

\(\frac{2010.125+1000}{126.2010-1010}=\frac{2010.125+1000}{2010.125+2010-1010}=\frac{2010.125+1000}{2010.125+1000}=\frac{1}{1}=1\)
