Multiplication practice worksheet focusing on numbers 0, 1, and 5.

Problem Description:

The task is to solve a series of multiplication problems involving the numbers 0, 1, and 5. The worksheet provides a grid of multiplication expressions, and the goal is to compute the results for each expression.

Solution Approach:

1. Understand the Properties of Multiplication:
- Any number multiplied by 0 results in 0.
- Any number multiplied by 1 remains unchanged (i.e., the result is the number itself).
- Multiplying by 5 involves multiplying the number by 5, which can be computed directly.

2. Solve Each Expression:
- For each multiplication problem, apply the appropriate rule or perform the calculation.

3. Organize the Results:
- Fill in the results in the corresponding boxes on the worksheet.

Step-by-Step Solution:

#### First Row (Multiplying by 0):
- \( 0 \times 7 = 0 \)
- \( 0 \times 9 = 0 \)
- \( 0 \times 4 = 0 \)
- \( 0 \times 2 = 0 \)

#### Second Row (Multiplying by 1):
- \( 1 \times 2 = 2 \)
- \( 1 \times 8 = 8 \)
- \( 1 \times 9 = 9 \)
- \( 1 \times 7 = 7 \)

#### Third Row (Multiplying by 1 and 5):
- \( 1 \times 1 = 1 \)
- \( 1 \times 6 = 6 \)
- \( 5 \times 3 = 15 \)
- \( 5 \times 5 = 25 \)

#### Fourth Row (Multiplying by 5):
- \( 5 \times 6 = 30 \)
- \( 5 \times 9 = 45 \)
- \( 5 \times 4 = 20 \)
- \( 5 \times 7 = 35 \)

Final Answers:

Here are the results for each multiplication problem:

| Expression | Result |
|------------|--------|
| \( 0 \times 7 \) | 0 |
| \( 0 \times 9 \) | 0 |
| \( 0 \times 4 \) | 0 |
| \( 0 \times 2 \) | 0 |
| \( 1 \times 2 \) | 2 |
| \( 1 \times 8 \) | 8 |
| \( 1 \times 9 \) | 9 |
| \( 1 \times 7 \) | 7 |
| \( 1 \times 1 \) | 1 |
| \( 1 \times 6 \) | 6 |
| \( 5 \times 3 \) | 15 |
| \( 5 \times 5 \) | 25 |
| \( 5 \times 6 \) | 30 |
| \( 5 \times 9 \) | 45 |
| \( 5 \times 4 \) | 20 |
| \( 5 \times 7 \) | 35 |

Final Answer:

\[
\boxed{
\begin{array}{cccc}
0 & 0 & 0 & 0 \\
2 & 8 & 9 & 7 \\
1 & 6 & 15 & 25 \\
30 & 45 & 20 & 35 \\
\end{array}
}
