Evaluate:
`24.55 div 20`

Answer

To evaluate \( 24.55 \div 20 \), we will follow these steps:

### Step 1: Set up the division
We start by writing the division in a long division format:
\[ 24.55 \div 20 \]

### Step 2: Divide the whole number part
First, we look at how many times 20 can go into 24.
- 20 goes into 24 once (1 time).
- Write 1 above the line.

### Step 3: Subtract and bring down the next digit
Now, subtract \( 20 \) from \( 24 \):
\[ 24 - 20 = 4 \]
Next, we bring down the next digit, which is 5, making it 45.

### Step 4: Divide the next part
Now, we see how many times 20 can go into 45.
- 20 goes into 45 two times (2 times).
- Write 2 above the line next to 1.

### Step 5: Subtract and bring down the next digit
Subtract \( 40 \) (which is \( 20 \times 2 \)) from \( 45 \):
\[ 45 - 40 = 5 \]
Now, we bring down the next digit, which is another 5, making it 55.

### Step 6: Divide again
Now, we see how many times 20 can go into 55.
- 20 goes into 55 two times (2 times).
- Write 2 above the line next to 12.

### Step 7: Subtract and bring down
Subtract \( 40 \) (which is \( 20 \times 2 \)) from \( 55 \):
\[ 55 - 40 = 15 \]
Now, we can bring down a 0, making it 150.

### Step 8: Divide again
Now, we see how many times 20 can go into 150.
- 20 goes into 150 seven times (7 times).
- Write 7 above the line next to 122.

### Step 9: Subtract and bring down
Subtract \( 140 \) (which is \( 20 \times 7 \)) from \( 150 \):
\[ 150 - 140 = 10 \]
Now, we bring down another 0, making it 100.

### Step 10: Final division
Now, we see how many times 20 can go into 100.
- 20 goes into 100 five times (5 times).
- Write 5 above the line next to 127.

### Step 11: Conclusion
Since there is no remainder left, we conclude that:
\[ 24.55 \div 20 = 1.2275 \]

### Final Answer:
\[ \text{The answer is } 1.2275. \]
