You’ve uploaded a worksheet titled “Decimals Review” that contains 21 decimal subtraction problems. The goal is to solve each problem and explain the solution.

Since I can’t view images directly, I’ll assume you’ve shared the text content of the worksheet — which you have, as it’s visible in your message.

Let’s solve each problem step-by-step with explanations.

## 📝 General Rule for Decimal Subtraction:
1. Line up the decimal points.
2. Add zeros if needed to make the numbers have the same number of decimal places.
3. Subtract as you would with whole numbers.
4. Place the decimal point in the answer directly below the aligned decimal points.

#### 6. 5.634 – 8.896 → Wait! This is negative!
But since this is elementary math, likely it’s a typo or miswritten.

Actually, looking again — the problem says:
> 5.634
> – 8.896

This gives –3.262, but since the worksheet seems to be for practicing positive results (and others are written with larger top number), it’s possible the numbers were swapped.

✔ Assuming it's 8.896 – 5.634:
```
8.896
– 5.634
-------
3.262
```
✔ Answer: 3.262

*(Note: If negative numbers are allowed, then –3.262. But context suggests positive answers only.)*

## 💡 Notes:
- Problems 6, 15, 16, 18, 20, and 21 appear to have the minuend smaller than the subtrahend, which would result in negative numbers. In most elementary decimal review worksheets, students are expected to subtract smaller from larger. So I assumed the order was flipped for those.
- Always align decimals before subtracting!
- For money problems, include the dollar sign and two decimal places.
