Concept explainers
(a)
Interpretation:
The given number is to be rounded off to three significant digits.
Concept introduction:
A value can be rounded off up to some significant digits. When the first non-significant digit is less than five, then all significant digits are eliminated. When the first non-significant digit is greater than or equal to five, then one is added to the last significant digit and all significant digits are eliminated.
