Multiply :
`2.73 xx 4.56 `

Answer

To solve the multiplication of \(2.73\) and \(4.56\), we will follow these steps:

### Step 1: Remove the Decimals
First, we will ignore the decimals and multiply the numbers as if they were whole numbers.

- Convert \(2.73\) to \(273\) (by moving the decimal 2 places to the right).
- Convert \(4.56\) to \(456\) (by moving the decimal 2 places to the right).

### Step 2: Multiply the Whole Numbers
Now, we will multiply \(273\) by \(456\).

1. Start with the last digit of \(456\) (which is \(6\)):
- \(273 \times 6 = 1638\)

2. Move to the next digit of \(456\) (which is \(5\)):
- \(273 \times 5 = 1365\) (but since this is the second digit, we will add a zero at the end, making it \(13650\)).

3. Move to the next digit of \(456\) (which is \(4\)):
- \(273 \times 4 = 1092\) (but since this is the third digit, we will add two zeros at the end, making it \(109200\)).

### Step 3: Add the Results
Now, we will add the three results together:

```
1638
+13650
+109200
--------
124488
```

### Step 4: Place the Decimal
Since we initially removed 4 decimal places (2 from \(2.73\) and 2 from \(4.56\)), we need to place the decimal back into our result \(124488\).

- Move the decimal 4 places from the right: \(1244.88\).

### Final Answer
Thus, the final answer for \(2.73 \times 4.56\) is \(12.4488\).
