Worksheet for practicing division of numbers in scientific notation with an answer key.

It looks like you've uploaded an image of a worksheet titled "Dividing numbers expressed in scientific notation", and it includes a grid of problems involving division of numbers in scientific notation. However, since I can't view images directly, I’ll need you to describe the specific problem or provide the exact expression you'd like me to solve.

That said, I can help you understand how to divide numbers in scientific notation and walk through an example step by step.

🔢 How to Divide Numbers in Scientific Notation:

To divide two numbers in scientific notation:

1. Divide the coefficients (the decimal parts).
2. Subtract the exponents of 10.
3. Express the result in proper scientific notation (i.e., coefficient between 1 and 10).

#### General Rule:
$$
\frac{a \times 10^m}{b \times 10^n} = \left(\frac{a}{b}\right) \times 10^{m-n}
$$

✔ Example Problem:

Let’s say one of the problems is:
$$
\frac{8 \times 10^5}{2 \times 10^3}
$$

Step 1: Divide the coefficients:
$$
\frac{8}{2} = 4
$$

Step 2: Subtract the exponents:
$$
10^{5-3} = 10^2
$$

Step 3: Combine:
$$
4 \times 10^2
$$

✔ Final Answer: $ 4 \times 10^2 $

If you can provide the specific problem from your worksheet (e.g., $ \frac{6 \times 10^7}{3 \times 10^4} $), I can solve it for you and explain each step.

Alternatively, if you're asking for help with the entire worksheet, please list a few problems or describe the pattern, and I’ll guide you through solving them.
