Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | tens | ones | . | tenths |
1 | 6 | , | 2 | |
- | 0 | , | 6 | |
, |
2. Subtract the numbers using long subtraction method
Because the upper digit (2) in the tenths 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 (12).
Place value | tens | ones | . | tenths |
5 | 12 | |||
1 | 6 | , | 2 | |
- | 0 | , | 6 | |
, |
Subtract the numbers in the tenths column from the top number:
12-6=6
Place value | tens | ones | . | tenths |
5 | 12 | |||
1 | 6 | , | 2 | |
- | 0 | , | 6 | |
, | 6 |
Subtract the numbers in the ones column from the top number:
5-0=5
Place value | tens | ones | . | tenths |
5 | 12 | |||
1 | 6 | , | 2 | |
- | 0 | , | 6 | |
5 | , | 6 |
Write 1 in the tens place.
Place value | tens | ones | . | tenths |
5 | 12 | |||
1 | 6 | , | 2 | |
