Thực hiện phép tính: 35/17 + - 9/5 + - 18/17 + 4/5

a) \(\ \frac{35}{17}+\frac{-9}{5}+\frac{-18}{17}+\frac{4}{5}\)

=\(\frac{35}{17}+\frac{-18}{17}+\frac{4}{5}+\frac{-9}{5}\)

= 1 - 1= 0

d) -3/14 x 4/13 + -3/14 x 9/13 + 3/4

= -3/14 x (4/13 + 9/13) + 3/4

= -3/14 x 1 + 3/4

= 15/28

e) 31/17 + -5/13 + -8/13 - 14/17

= ( 31/17 - 14/17) +(-5/13+-8/13)

= 1 - 1 = 0

f) -5/7 x 2/11 + -5/7 x 9/11 + 5/7

= -5/7 x (2/11 + 9/11) + 5/7

= -5/7 x 1 + 5/7

= 0

tiếp ik ạ

c) 26/15 + -7/13 + -6/13 - 11/15

= (26/15 - 11/15) + (-7/13 - 6/13)

= 1 - 1 = 0
