Concept explainers
(a)
Interpretation:
The given number
Concept Introduction:
Rounding off a number:
- The last digit retained is left unchanged if the following digit is less than five.
- The last digit retained is increased by one if the following digit is greater than five.
- If the last digit retained is followed by a single digit of five or by a five followed by zeroes, then the last digit is increased by one if it is odd number and remains as same if it is even number.
(b)
Interpretation:
