1. 5/9-4/3x= 1/3

   <=> 4/3x= 5/9-1/3

   <=> 4/3x= 2/9

   <=> x= 2/9:4/3

   <=> x= 1/6

   Vậy x= 1/6

   -5/4×3/13-5/4:13/10

   = -5/4×3/13+5/4×10/13

   = -5/4×(3/13+10/13)

   = -5/4×1

   = -5/4

2. 5/9-4/3x=1/3

   4/3x=5/9-1/3

   4/3x=5/9-3/9

   4/3x=2/9

   x=2/9:4/3

   x=2/9. 3/4

   x=1/6

   Vậy  x=1/6

   (-5/4). 3/13-5/4:13/10

   =(-5/4). 3/13+(-5/4). 10/13

   =(-5/4). (3/13+10/13)

   =(-5/4).1

   =-5/4
