11,3
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths |
| 1 | 4 | , | 6 | |
| 0 | , | 4 | ||
| - | 2 | , | 9 | |
| , |
2. Subtract the numbers using long subtraction method
Because the upper digit (6) in the tenths column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (16).
| Place value | tens | ones | . | tenths |
| 3 | 16 | |||
| 1 | 4 | , | 6 | |
| 0 | , | 4 | ||
| - | 2 | , | 9 | |
| , |
Subtract the numbers in the tenths column from the top number:
16-4-9=3
| Place value | tens | ones | . | tenths |
| 3 | 16 | |||
| 1 | 4 | , | 6 | |
| 0 | , | 4 | ||
| - | 2 | , | 9 | |
| , | 3 |
Subtract the numbers in the ones column from the top number:
3-0-2=1
| Place value | tens | ones | . | tenths |
| 3 | 16 | |||
| 1 | 4 | , | 6 | |
| 0 | , | 4 | ||
| - | 2 | , | 9 | |
| 1 | , | 3 |
Write 1 in the tens place.
| Place value | tens | ones | . | tenths |
| 3 | 16 | |||
| 1 | 4 | , | 6 | |
| 0 | , | 4 | ||
| - | 2 | , | 9 | |
| 1 | 1 | , | 3 |
The solution is: 11,3
