Question 9

Which reading is exactly equal to 5.07?

  1. 5.7
  2. 5.070Bonne réponse
  3. 5.007
  4. 5.700

Explication

Appending a trailing zero gives 5.07 = 5.070 because the added zero has no nonzero digit after it. The value 5.7 puts the 7 in tenths instead of hundredths and is therefore larger.
