2 bình luận về “Tìm x x : 1/2 = 2/3 x 4/5 x 3/4 x 15/8”

1. x:1/2=2/3×4/5×3/4×15/8

   x:1/2=8/15×3/4×15/8

   x:1/2=24/60×15/8

   x:1/2=2/5×15/8

   x:1/2=30/40

   x:1/2=3/4

   x      =3/4×1/2

   x      =3/8

          Vậy x=3/8

2. x: 1/2 = 2/3 xx 4/5 xx 3/4 xx 15/8

   x : 1/2 =8/15 xx 3/4 xx15/8

   x: 1/2 = (8/15 xx 15/8) xx 3/4

   x: 1/2 = 1 xx3/4

   x= 3/4 xx 1/2

   x= 3/8

   Vậy x = 3/8
