(a)
Interpretation: The correct number of significant figure has to be given..
Concept introduction:
Significant of zeroes:
- Zeroes between two other significant digits are significant.
- Zeroes to the right of a nonzero number, and also to the right of decimal place, are significant.
- Zeroes that are placeholders are not significant.
Rules used for significant figures in calculations:
Rule 1: When adding or subtracting numbers, the number of decimal places in the answer is equal to the number of decimal places in the number with fewest digits after the decimal.
Rule 2: In multiplication or division, the number of significant figures in the answer is determined by the quantity with the fewest significant figures.
Rule 3: When a number is rounded off, the last digit to be retained is increased by one only if the following digit is 5 or greater.
