Incorrect Rule Regarding Significant Figures in Calculations
Explanation:
The significant figures are the reliable digits in a number obtained by measurement or calculation. The rules of significant figures are used to determine the precision of the measurement or calculated data. These rules are as follows:
a) Addition or Subtraction:
When two or more numbers are added or subtracted, the result should be reported with the same number of decimal places as the number with the least number of decimal places.
Example:
5.63 + 4.1 = 9.73 (rounded to 9.7)
b) Multiplication or Division:
When two or more numbers are multiplied or divided, the result should have the same number of significant figures as the number with the least significant figures.
Example:
5.63 × 4.1 = 23.083 (rounded to 23)
c) Rounding off:
The result of a calculation should be rounded off to the same number of significant figures as the least precise measurement.
Example:
6.4 cm × 3.2 cm = 20.48 cm² (rounded to 20 cm²)
d) Non-significant figures:
The non-significant figures in a measurement should be rounded off to the nearest value.
Example:
5.623 cm (rounded to 5.62 cm)
The correct answer is option B, which states that the result of multiplication or division should have the same number of significant figures as the most precise figure. This is incorrect because the result of multiplication or division should have the same number of significant figures as the least precise figure.

The correct answer is option B, which states that the result of multiplication or division should have the same number of significant figures as the most precise figure. This is incorrect because the result of multiplication or division should have the same number of significant figures as the least precise figure.
