Question 47

What number must be added to 1.47 to make 4.2?

  1. 2.63
  2. 3.27
  3. 2.73Bonne réponse
  4. 3.73

Explication

The missing addend is the difference 4.20 - 1.47 = 2.73, and checking gives 1.47 + 2.73 = 4.20. The value 3.27 reverses decimal digits after subtraction rather than borrowing through aligned places.
