Solution - Long subtraction
Other Ways to Solve:
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 3 | . | 7 | ||||
| - | 2 | . | 9 | 1 | 3 | 3 |
| . |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 3 | . | 7 | 0 | 0 | 0 | |
| - | 2 | . | 9 | 1 | 3 | 3 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the ten thousandths column is too small to get a positive difference, borrow 1 from the number to the left (700) which becomes (699) and get (10).
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | 9 | 9 | 10 | |||
| 3 | . | 7 | 0 | 0 | 0 | |
| - | 2 | . | 9 | 1 | 3 | 3 |
| . |
Subtract the numbers in the ten thousandths column from the top number:
10-0-3=7
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | 9 | 9 | 10 | |||
| 3 | . | 7 | 0 | 0 | 0 | |
| - | 2 | . | 9 | 1 | 3 | 3 |
| . | 7 |
Subtract the numbers in the thousandths column from the top number:
9-3=6
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | 9 | 9 | 10 | |||
| 3 | . | 7 | 0 | 0 | 0 | |
| - | 2 | . | 9 | 1 | 3 | 3 |
| . | 6 | 7 |
Subtract the numbers in the hundredths column from the top number:
9-1=8
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths |
| 6 | 9 | 9 | 10 | |||
| 3 | . | 7 | 0 | 0 | 0 | |
| - | 2 | . | 9 | 1 | 3 | 3 |
| . | 8 | 6 | 7 |
Because the upper digit (6) in the tenths column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (16).

The solution is: 0.7867
