Solution - Long subtraction
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | tens | ones | . | tenths | hundredths | thousandths |
1 | 5 | . | 7 | 6 | ||
- | 9 | . | 1 | 3 | 4 | |
. |
Put zeros in the blank number places:
Place value | tens | ones | . | tenths | hundredths | thousandths |
1 | 5 | . | 7 | 6 | 0 | |
- | 9 | . | 1 | 3 | 4 | |
. |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the thousandths 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).

Because the upper digit (5) in the ones 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 (15).

Subtract the numbers in the ones column from the top number:
15-9=6
