Sagot :
Let's perform the division of [tex]\(0.0016\)[/tex] by [tex]\(0.849\)[/tex] and report the result to the correct number of significant figures.
### Step-by-Step Solution:
1. Identify the Numbers Involved:
- Numerator: [tex]\(0.0016\)[/tex]
- Denominator: [tex]\(0.849\)[/tex]
2. Perform the Division:
[tex]\[ \frac{0.0016}{0.849} = 0.0018845700824499413 \][/tex]
3. Determine the Significant Figures:
- The number [tex]\(0.0016\)[/tex] has 2 significant figures.
- The number [tex]\(0.849\)[/tex] has 3 significant figures.
4. Select the Correct Number of Significant Figures for the Result:
- The result should be reported to the least number of significant figures between the two numbers, which is 2 significant figures.
5. Round the Result to 2 Significant Figures:
- The result from the division is approximately [tex]\(0.0018845700824499413\)[/tex].
- Rounding [tex]\(0.0018845700824499413\)[/tex] to 2 significant figures gives [tex]\(0.0019\)[/tex].
### Final Answer:
[tex]\[ 0.0016 \div 0.849 = 0.0019 \][/tex]
The result of the division [tex]\(0.0016 \div 0.849\)[/tex], reported to the correct number of significant figures, is [tex]\(0.0019\)[/tex].
