EXPLANATION OF ANSWERS

  1. The child rounded off to the nearest whole number when he's supposed to round of to the nearest tenths.
  2. This is correct. Since the number beside 9 on the right is 4, we retain the number.
  3. You are supposed to retain the number when the value beside the number you will be rounding off is 4 or less.
  4. When the value beside the number you're rounding off is 5 or more, add 1 to the number. Since the number beside 7 is 6, you are supposed to add 1 to the number.
  5. This is correct. (refer to former explanations about rounding off with number that is 5 or more)
  6. This is correct. (refer to former explanations about rounding off with number that is 5 or more)
  7. This is wrong. (refer to former explanations about rounding off with number that is 4 or less)
