Arrange the following decimals in descending order:
6.5, 6.05, 6.54, 6.4 and 6.45

Answer

To arrange the decimals 6.5, 6.05, 6.54, 6.4, and 6.45 in descending order, we will follow these steps:

### Step 1: Write down the decimals
We have the following decimals to arrange:
- 6.5
- 6.05
- 6.54
- 6.4
- 6.45

### Step 2: Compare the whole numbers
All the decimals have the same whole number part (6), so we will focus on the decimal parts.

### Step 3: Compare the decimal parts
The decimal parts of each number are:
- 6.5 → 0.5
- 6.05 → 0.05
- 6.54 → 0.54
- 6.4 → 0.4
- 6.45 → 0.45

### Step 4: Arrange the decimal parts in descending order
Now, we will arrange the decimal parts from largest to smallest:
- 0.54 (from 6.54)
- 0.5 (from 6.5)
- 0.45 (from 6.45)
- 0.4 (from 6.4)
- 0.05 (from 6.05)

### Step 5: Write the decimals in descending order
Now we can write the original decimals in descending order based on the arrangement of their decimal parts:
1. 6.54
2. 6.5
3. 6.45
4. 6.4
5. 6.05

### Final Answer
The decimals arranged in descending order are:
**6.54, 6.5, 6.45, 6.4, 6.05**
