Select all transformations that preserve the stated equality.

  1. 3.6 x 0.1 = 0.36Bonne réponse
  2. 45 / 1000 = 0.45
  3. 0.72 / 0.1 = 7.2Bonne réponse
  4. 0.09 x 100 = 0.9

Explication

Both 3.6 x 0.1 = 0.36 and 0.72 / 0.1 = 7.2 apply the inverse roles of one tenth correctly. The equations 45 / 1000 = 0.45 and 0.09 x 100 = 0.9 each move the point too few places.
