Verified step by step guidance1
Identify the number of significant figures in each number involved in the division. For 8.64, count the digits that are significant.
For 2.0, determine the number of significant figures, noting that the trailing zero after the decimal point counts as significant.
Recall the rule for multiplication and division: the result should have the same number of significant figures as the number with the fewest significant figures in the calculation.
Compare the significant figures of 8.64 and 2.0 to find the smaller number of significant figures.
Conclude that the answer should be rounded to the number of significant figures equal to the smaller count found in the previous step.
