giúp tớ ạ

Answer 1

\(\dfrac{13}{25}-\dfrac{5}{9}-\dfrac{38}{25}+\dfrac{14}{9}\\ =\left(\dfrac{13}{25}-\dfrac{38}{25}\right)+\left(\dfrac{14}{9}-\dfrac{5}{9}\right)\\ =-\dfrac{25}{25}+\dfrac{9}{9}=-1+1=0\)

Answer 2

13/25 - 5/9 - 38/25 + 14/9

= (13/25 - 38/25) + (14/9 - 5/9)

= -25/25 + 9/9

= -1 + 1 = 0

Answer 3

13/25 - 5/9 - 38/25 + 14/9

=(13/25 - 38/25) + (14/9 - 5/9)

= - 25/25 + 9/9 = -1 + 1 = 0
