1. a) x + 5/2 × 2/3 = 5/2

   x + 5/3 = 5/2

   x = 5/2 – 5/3

   x = 15/6 – 10/6

   x = 5/6

   b) 23/6 😡 – 2/5 = 1/4

   23/6 : x = 1/4 + 2/5

   23/6 : x = 5/20 + 8/20

   23/6 : x = 13/20

   x = 13/20 × 23/6

   x = 299/120

   _Phòng sai đề:

   3/6 : x – 2/5 = 1/4

   3/6 : x = 1/4 + 2/5

   3/6 : x = 5/20 + 8/20

   3/6 : x = 13/20

   x = 13/20 × 3/6

   x = 13/40
