\(\frac{2006.125+1000}{126.2005-888}=\frac{250750+1000}{252630-888}=\frac{125875}{125871}\)

125875/125871

\(\frac{2006\cdot125+1000}{126\cdot2005-888}=\frac{(2005+1)\cdot125+1000}{(125+1)\cdot2005-888}\)

                                    \(=\frac{2005\cdot125+125\cdot1000}{125\cdot2005+2005-888}\)

                                      \(=\frac{2005\cdot125+1125}{125\cdot2005+1117}=\frac{1125}{1117}\)

Vậy : \(\frac{2006\cdot125+1000}{126\cdot2005-888}=\frac{1125}{1117}\)

\(\frac{2004.2006+1000}{2005.2006-1006}\)

\(=\frac{2004.2006+1000}{\left(2004+1\right).2006-1006}\)

\(=\frac{2004.2006+1000}{2004.2006+2006-1006}\)

\(=\frac{2004.2006+1000}{2004.2006+1000}\)

\(=1\)

\(\frac{2004x2006+1000}{2005x2006-1006}\)

=\(\frac{1000}{1x2006-1006}\)cùng giảm 2004 lần số 2006

=\(\frac{1000}{1000}=1\)

\(\frac{2006x125+1000}{126x2006-1006}=\frac{2006x125+1000}{125x2006-2006-1006}=\frac{2006x125+1000}{125x2006+1000}=1\)

=\(\frac{2006x125+1000}{125x2006+2006-1006}\)

=\(\frac{2006x125+1000}{125x2006+1000}\)

=1

\(\frac{2006\cdot125+1000}{126\cdot2006-1006}=\frac{2006\cdot\left(126-1\right)+1000}{126\cdot2006-1006}\)

\(=\frac{2006\cdot126-2006+1000}{126\cdot2006-1006}\)

\(=\frac{2006\cdot126-1006}{126\cdot2006-1006}\)

\(=1\)

\(\frac{2006x125+1000}{126x2006-1006}\)

\(=\frac{2006x125+1000}{\left(125+1\right)x2006-1006}\)

\(=\frac{2006x125+1000}{125x2006+1x2006-1006}\)

\(=\frac{2006x125+1000}{125x2006+2006-1006}\)

ạ) \(136.75+75.64=75.\left(136+64\right)=75.200=15000\)

b) \(\frac{2006.125+1000}{126.2005-880}=\frac{2005.125+125+1000}{125.2005+2005-880}=\frac{2005.125+1125}{125.2005+1125}=1\)

a) 136 . 75 + 75 . 64 

= 75 . ( 136 + 64 )

= 75 . 200

= 15 000

\(\frac{2006\times125+100}{125\times200-880}=\frac{250850}{24120}\)

2006 x 125 + 100/125 x 200 - 880
