\(\frac{\left(2005+1\right).125+1000}{\left(125+1\right).2005-888}\)
= \(\frac{2005.125+125+1000}{125.2005+2005-888}\)
= \(\frac{2005.125+1125}{125.2005+1117}\)
= \(\frac{250625+1125}{250625+1117}\)
= \(\frac{125875}{125871}\)
\(\frac{\left(2005+1\right).125+1000}{\left(125+1\right).2005-888}\)
= \(\frac{2005.125+125+1000}{125.2005+2005-888}\)
= \(\frac{2005.125+1125}{125.2005+1117}\)
= \(\frac{250625+1125}{250625+1117}\)

Bài 2 : Tính nhanh
a, 15\(\dfrac{2121}{4343}\)+15*\(\dfrac{222222}{434343}\)
b, A=\(\dfrac{2006\cdot125+1000}{126\cdot2005-888}\)
Tính nhanh :
\(\frac{2006\times125+1000}{126\times2005-888}\)
tính nhanh :
2006*125+1000
126*2005-888
2006 x 125 + 1000 / 126 x 2005 - 888
Tính nhanh:
\(\frac{2006\cdot2007-1997}{2006\cdot2005+2015}\)
Tính nhanh:
B= 2006 * 125 =1000 / 126 * 2005 -880
Các bạn giúp mình với nha
