The Number 7.325 Rounded Off to Three Significant Figures

In scientific notation and engineering calculations, it is often necessary to round numbers to a specified number of significant figures. Significant figures are the digits in a number that are known with certainty, plus one estimated digit. The number of significant figures in a number is determined by the following rules:

All non-zero digits are significant.
Zeros between non-zero digits are significant.
Zeros at the beginning of a number are not significant.
Zeros at the end of a number are significant if there is a decimal point.

For example, the number 123 has three significant figures, while the number 0.0012 has two significant figures.

Rounding the Number

To round the number 7.325 to three significant figures, we first identify the three most significant digits. These are the digits 7, 3, and 2. The fourth digit, 5, is not significant because it is not one of the three most significant digits.

The rounded number is then obtained by dropping the insignificant digits. In this case, we drop the digit 5. The rounded number is therefore 7.32.
