The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. This means you MUST know how to recognize significant figures in order to use this rule. Example #1: 2.5 x 3.42.

How do you find sig figs with division?

When multiplying and dividing numbers with significant figures the answer should be rounded to the same number of significant figures as the number with?

For multiplication and division problems, the answer should be rounded to the same number of significant figures as the measurement with the least number of significant figures. Applying this rule results in a density of 2.95 g/cm³, for three significant figures – the same as the volume measurement.
