1,1111x1,22222

To solve the multiplication of 1,1111 and 1,22222, we can proceed by multiplying the two numbers step by step.

First, let's align the numbers for clarity:

```
1.1111
x 1.22222
```

Next, we can ignore the decimals for now and multiply them as if they were whole numbers:

```
11111
x 122222
```

Now we proceed with the multiplication using the standard algorithm.

1. Multiply 11111 by 2 (the digit in the ones place of 122222):
- 11111 * 2 = 22222

2. Multiply 11111 by 2 (the digit in the tens place of 122222):
- 11111 * 2 = 22222 (and shift one position to the left)
- This results in 222220.

3. Multiply 11111 by 2 (the digit in the hundreds place of 122222):
- 11111 * 2 = 22222 (and shift two positions to the left)
- This results in 2222200.

4. Multiply 11111 by 2 (the digit in the thousands place of 122222):
- 11111 * 2 = 22222 (and shift three positions to the left)
- This results in 22222000.

5. Multiply 11111 by 1 (the digit in the ten-thousands place of 122222):
- 11111 * 1 = 11111 (and shift four positions to the left)
- This results in 111110000.

Now we add all these partial products together:

```
22222
+ 222220
+ 2222200
+ 22222000
+ 111110000
```

Aligning the numbers correctly, we get:

```
22222
222220
2222200
22222000
+111110000
-----------
136975000
```

Now we have the product as a whole number: 136975000.

Since both of the original numbers had decimals, we need to determine where the decimal point should go in our final answer.

1.1111 has 4 decimal places, and 1.22222 has 5 decimal places, for a total of 4 + 5 = 9 decimal places.

Thus, we place the decimal point 9 places from the right in our final product, yielding:

Final Answer: 136.975

So, 1.1111 x 1.22222 = 1.36975.
