Significant Figures in Division: A Step-by-Step Guide to Avoiding Errors - starpoint
Significant figures in division refer to the number of digits in a result that are reliable and certain. When dividing numbers, the number of significant figures in the result is limited by the smallest number of significant figures in the two numbers being divided. For example, if you divide 12.3 by 4.5, the result, 2.733..., has three significant figures.
What happens when dividing by a number with more decimal places?
However, failing to understand significant figures in division can result in:
Accurately applying significant figures in division can lead to:
