Since I can't view or access images directly, I can’t see the specific multiplication problems in your image. However, based on the text you've provided, it looks like a worksheet with 24 decimal multiplication problems (e.g., 22.59 × 40.19, 14.49 × 17.45, etc.).

Let me help you solve one example problem step-by-step, and then I’ll give you guidance on how to solve all of them.

🔢 Example Problem:


22.59 × 40.19

#### Step 1: Ignore decimals and multiply as whole numbers
First, treat both numbers as whole numbers:
```
2259
× 4019
-------
```

We'll do this multiplication step by step:

```
2259
× 4019
-------
2259 ← 2259 × 9
2259 ← 2259 × 1 (shifted one place left)
0 ← 2259 × 0 (shifted two places left)
9036 ← 2259 × 4 (shifted three places left)
-------
```

Now compute each part:

- 2259 × 9 = 20,331
- 2259 × 1 = 2,259 → shifted to 22,590
- 2259 × 0 = 0 → 0
- 2259 × 4 = 9,036 → shifted to 903,600

Now add them up:

```
20,331
+ 22,590
+ 0
+ 903,600
----------
946,521
```

So, 2259 × 4019 = 946,521

#### Step 2: Count decimal places
- 22.59 has 2 decimal places
- 40.19 has 2 decimal places
- Total = 4 decimal places

#### Step 3: Place the decimal point
Take 946,521 and move the decimal 4 places from the right:
946.5210 → but we only need 4 digits after decimal, so:

Wait — actually, since we had 4 decimal places total, we place the decimal 4 places from the right:
946.5210 → but that’s not correct because:

Wait! Let's recheck:
22.59 × 40.19 = ?

Actually, better to use calculator-style precision.

But let's double-check with actual multiplication:

Alternatively, use estimation:
- 22.59 ≈ 22.6
- 40.19 ≈ 40.2
- 22.6 × 40.2 ≈ ?

22.6 × 40 = 904
22.6 × 0.2 = 4.52
Total ≈ 908.52 → So answer should be around 908.5

Wait — our earlier calculation gave 946,521, which is for 2259 × 4019, but we need to account for decimals.

We have:
- 22.59 = 2259 / 100
- 40.19 = 4019 / 100
- So product = (2259 × 4019) / 10,000

We already calculated:
2259 × 4019 = 946,521

So:
946,521 ÷ 10,000 = 94.6521

So, 22.59 × 40.19 = 94.6521

Final Answer: 94.6521

Now, here’s how to solve all the problems on the sheet:

🔧 General Steps for Decimal Multiplication:



1. Ignore decimals and multiply the numbers as if they were whole numbers.
2. Count total decimal places in both numbers.
3. Place the decimal point in the product so that it has the same number of decimal places as the sum of the decimal places in the original numbers.

📌 Let’s do one more example:



14.49 × 17.45

Step 1: Multiply 1449 × 1745

Use calculator or long multiplication:
1449 × 1745 = ?

Or estimate:
14.49 × 17.45 ≈ 14.5 × 17.5 = (14 × 17.5) + (0.5 × 17.5) = 245 + 8.75 = 253.75

Actual:
1449 × 1745 = ?

Break it down:
1449 × 1700 = 1449 × 17 × 100 = (1449 × 10 = 14,490; 1449 × 7 = 10,143; total = 14,490 + 10,143 = 24,633) × 100 = 2,463,300

Then 1449 × 45 = 1449 × 40 + 1449 × 5 = 57,960 + 7,245 = 65,205

Total = 2,463,300 + 65,205 = 2,528,505

Now, decimal places:
- 14.49 → 2
- 17.45 → 2
- Total = 4

So, 2,528,505 → move decimal 4 places left → 252.8505

So, 14.49 × 17.45 = 252.8505

Summary:



To solve all 24 problems:

1. For each pair, multiply the numbers as whole numbers.
2. Count decimal places in both factors.
3. Place the decimal in the product accordingly.

💡 Tips:


- Use a calculator if allowed.
- Estimate first to check reasonableness.
- Always count decimal places carefully.
