\(\frac{\text{2006 x 125 + 1000}}{\text{ 2005 x 126 - 880}}=???\)

Trả lời :

\(\frac{\text{2006 x 125 + 1000}}{\text{2005 x 126 - 880}}=\frac{\text{251750}}{\text{251750}}=1\)

Chúc bạn học tốt !

\(B=\frac{2006\cdot125+1000}{126\cdot2005-880}\)

= \(\frac{2005\cdot125+125+1000}{2005\cdot126-880}=\frac{2005\cdot125+1125}{2005\cdot126-880}\)

=\(\frac{2005\cdot125+1125}{2005\cdot125+125-880}=1,007523912\)

a, 5/3*4/7*3/5*7/8

= (5/3*3/5)*(4/7*7/8)

= 1*1/2

=1/2

b, 2006*125+1000/126*2005-880

= (2005+1)*125+1000/126*2005-880

=2005*125+125+1000/126*2005-880

=2005*(125+1000/126)-880+125

=2005*8375/63-880+125

=266537,6984-880+125

=265657,6984+125

=265782,6984

a,  ( 32,5 + 28,3 X 2,7 - 108,91 ) X 2006
= (32,5 + 76,41 - 108,91)X 2006
= (108,91 - 108,91) X 2006
= 0 X 2006
= 0

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

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

2006 x 125 + 100/125 x 200 - 880

nhấn vào chữ x là dấu nhân thui bạn

đấy dấu nhân  mk vừa viết là chữ x đấy , đây nè : x

lúc đầu mk cx chẳng bít , xong mk tự nghĩ ra đây !! hihi

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

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

=2010 x 125 + 2010x 126 + 1000+1010

=2010 x 125 + 2010 x 126 + 2010

=2010 x ( 125 + 126 +1 )

=2010 x 252

=506520

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

\(\frac{2006\cdot125+1000}{126\cdot2005-888}=\frac{2005\cdot125+125+1000}{125\cdot2005+2005-888}=\frac{2005\cdot125+1125}{125\cdot2005+1117}\)

=> không tính nhanh được

\(\frac{125875}{125871}\)
