Solution - Long subtraction
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 | hundred thousandths | millionths | ten millionths | hundred millionths | billionths |
| 0 | . | 0 | 0 | 0 | 1 | 4 | 7 | 4 | |||
| - | 0 | . | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 6 | 7 |
| . |
Put zeros in the blank number places:
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths | hundred millionths | billionths |
| 0 | . | 0 | 0 | 0 | 1 | 4 | 7 | 4 | 0 | 0 | |
| - | 0 | . | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 6 | 7 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the billionths column is too small to get a positive difference, borrow 1 from the number to the left (40) which becomes (39) and get (10).
