Question 35

What is 8.249 rounded directly to one decimal place?

  1. 8.24
  2. 8.25
  3. 8.3
  4. 8.2Bonne réponse

Explication

The hundredths digit is 4, so direct rounding keeps the tenths digit and gives 8.2. The result 8.3 comes from first turning 8.249 into 8.25 and then rounding again, which is the banned double-rounding route.
