Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 2 | 0 | , | 3 | 4 | |
| - | 1 | 1 | 3 | , | 7 | 2 |
| , |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
4-2=2
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 1 | 2 | 0 | , | 3 | 4 | |
| - | 1 | 1 | 3 | , | 7 | 2 |
| , | 2 |
Because the upper digit (3) in the tenths column is too small to get a positive difference, borrow 1 from the number to the left (20) which becomes (19) and get (13).
