Answer :
To solve the problem of dividing 12.0 by 7.11 and expressing the answer with the correct number of significant figures, follow these steps:
1. Identify Significant Figures:
- The number 12.0 has 3 significant figures.
- The number 7.11 also has 3 significant figures.
2. Perform the Division:
- Divide 12.0 by 7.11 to get approximately 1.68776371308.
3. Determine Significant Figures for the Result:
- In division, the number of significant figures in the result should be the same as the number with the fewest significant figures used in the calculation. In this case, both numbers have 3 significant figures.
4. Round to the Correct Number of Significant Figures:
- We round 1.68776371308 to three significant figures, which gives us 1.69.
Therefore, the solution, expressed with the correct number of significant figures, is 1.69, which matches option B.
