Answer: 4.3
Explanation: Given: 8.64 is to be divided by 2.0.
Thus \(\frac{8.64}{2.0}=4.32\)
By using the rules for significant figures for division, the least number of significant figures in any number of the problem determines the number of significant figures in the answer.
8.64 has three significant digits and 2.0 has two significant figures, thus 2.0 is least precise and the answer should also have two significant digits.Thus the answer should be 4.3.
