Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | |
| , |
Put zeros in the blank number places:
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
9-0=9
| Place value | tens | ones | . | tenths | hundredths |
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| , | 9 |
Because the upper digit (1) in the tenths column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (11).
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 11 | ||||
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| , | 9 |
Subtract the numbers in the tenths column from the top number:
11-3=8
| Place value | tens | ones | . | tenths | hundredths |
| 0 | 11 | ||||
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| , | 8 | 9 |
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the digit (6) in the next number place which becomes (5) and get (10).
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 10 | ||||
| 0 | 11 | ||||
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| , | 8 | 9 |
Subtract the numbers in the ones column from the top number:
10-4=6
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 10 | ||||
| 0 | 11 | ||||
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| 6 | , | 8 | 9 |
Subtract the numbers in the tens column from the top number:
5-1=4
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 10 | ||||
| 0 | 11 | ||||
| 6 | 1 | , | 1 | 9 | |
| - | 1 | 4 | , | 3 | 0 |
| 4 | 6 | , | 8 | 9 |
The solution is: 46,89
