Answer :

To solve the problem [tex]\(\frac{1}{2.67 \times 10^{11}}\)[/tex] and express the answer in scientific notation with 2 decimal places, we follow these steps:

1. Understand the Division: We need to divide the number 1 by [tex]\(2.67 \times 10^{11}\)[/tex]. This is essentially finding how many times [tex]\(2.67 \times 10^{11}\)[/tex] fits into 1.

2. Perform the Division:
[tex]\[ \frac{1}{2.67 \times 10^{11}} \][/tex]
Conceptually, this division operation will result in a very small number because the numerator (1) is much smaller compared to the denominator ([tex]\(2.67 \times 10^{11}\)[/tex]).

3. Calculate the Result: When we divide 1 by [tex]\(2.67 \times 10^{11}\)[/tex], we obtain a result of approximately:
[tex]\[ 3.745318352059925 \times 10^{-12} \][/tex]

4. Express in Scientific Notation:
To express this result in scientific notation with 2 decimal places, we need to round the number [tex]\(3.745318352059925\times 10^{-12}\)[/tex] to two decimal places.

- Look at the digits beyond the second decimal place (which are [tex]\(5318352059925\)[/tex] in this case).
- If the digit immediately after the second decimal place (which is 5 here) is 5 or more, we round up the second decimal place.

Using this rounding procedure, [tex]\(3.745318352059925 \times 10^{-12}\)[/tex] rounds to:
[tex]\[ 3.75 \times 10^{-12} \][/tex]

5. Final Answer:
Therefore, the result of [tex]\(\frac{1}{2.67 \times 10^{11}}\)[/tex] when expressed in scientific notation with 2 decimal places is:
[tex]\[ 3.75 \times 10^{-12} \][/tex]

Thus, the final answer is [tex]\(3.75 \times 10^{-12}\)[/tex].
