1. `a)x+3/4=8/16`

       `x+3/4=1/2`

       `x=1/2-3/4`

       `x=2/4-3/4`

       `x=-1/4`

   `b)x:3/7=35/3`

       `x=35/3 . 3/7`

       `x=105/21`

       `x=5`

   `c)x. 4/8=8/4`

      `x=8/4:4/8`

      `x=8/4 . 8/4`

      `x=64/16`

      `x=4`

2. Đáp án:

    

   Giải thích các bước giải:

   `a)“x + 3/4 = 8/16`

   `x = 8/16 – 3/4`

   `x = 2/4 – 3/4`

   `x = -1/4`

   `b)“x : 3/7 =35/3`

   `x = 35/3 × 3/7`

   `x = 5/1 × 1/1`

   `x = 5/1 = 5`

   `c)“x × 4/8 = 8/4`

   `x = 8/4 : 4/8`

   `x = 8/4 ×8/4`

   `x = 2/1 × 2/1`

   `x = 4/1 = 4`
