3/17 - 5/13 - 18/35 + 14/17 + 17/-35 - 8/13
=(3/17+14/17)+(-5/13-8/13)+(-18/35+17/35)
=1+(-1)+(-1/35)
=-1/35
Chúc bn học tốt
\(\frac{3}{17}-\frac{5}{13}-\frac{18}{35}+\frac{14}{17}\)\(+\frac{17}{-35}-\frac{8}{13}\)
\(=\left(\frac{3}{17}+\frac{14}{17}\right)\)\(-\left(\frac{18}{35}-\frac{-17}{35}\right)\)\(-\left(\frac{5}{13}+\frac{8}{13}\right)\)
\(=1-1-1\)\(=0\)
lớp mấy vậy??? lớp 7 thì sai sai
=(3/17+14/17)-( 18/35-17/35 )+(5/13-8/13) =1-1-1
= -1
