1. 5/12 + 5/12 x 4

   = 5/12 + 20/12

   = (5 + 20) / 12

   = 25/12

   Vậy 5/12 + 5/12 x 4 = 25/12

   5/12 + 5/12 x 6

   = 5/12 + 30/12

   = (5 + 30) / 12

   = 35/12

   Vậy 5/12 + 5/12 x 6 = 35/12

   5/7 + 1/2 x 2 x 4/5

   = 5/7 + 2/2 x 4/5

   = 5/7 + 1 x 4/5

   = 5/7 + 4/5

   = 25/35 + 28/35

   = (25 + 28) / 35

   = 53/35

   Vậy 5/7 + 1/2 x 2 x 4/5 = 53/35

   5/12 x 5/12 x 5/12

   = 25/144 x 5/12

   = 125/1728

   Vậy 5/12 x 5/12 x 5/12 = 125/1728

2. -5/12 + 5/12 * 4 = 5/12 + 10/6 = 25/12

   -5/12 + 5/12 * 6 = 5/12 + 15/6 = 35/12

   -5/7 + 1/2 * 2 * 4/5 = 5/7 + 4/5 = 53/35

   -5/12 * 5/12 * 5/12 = 125/1728

   Nhớ cho mình câu trả lời hay nhất nhé
