Solution - Long subtraction
1.77
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | ones | . | tenths | hundredths |
1 | . | 8 | ||
- | 0 | . | 0 | 3 |
. |
Put zeros in the blank number places:
Place value | ones | . | tenths | hundredths |
1 | . | 8 | 0 | |
- | 0 | . | 0 | 3 |
. |
2. Subtract the numbers using long subtraction method
Because the upper digit (0) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (8) in the next number place which becomes (7) and get (10).
Place value | ones | . | tenths | hundredths |
7 | 10 | |||
1 | . | 8 | 0 | |
- | 0 | . | 0 | 3 |
. |
Subtract the numbers in the hundredths column from the top number:
10-0-3=7
Place value | ones | . | tenths | hundredths |
7 | 10 | |||
1 | . | 8 | 0 | |
- | 0 | . | 0 | 3 |
. | 7 |
Subtract the numbers in the tenths column from the top number:
7-0=7
Place value | ones | . | tenths | hundredths |
7 | 10 | |||
1 | . | 8 | 0 | |
- | 0 | . | 0 | 3 |
. | 7 | 7 |
Subtract the numbers in the ones column from the top number:
1-0=1
Place value | ones | . | tenths | hundredths |
7 | 10 | |||
1 | . | 8 | 0 | |
- | 0 | . | 0 | 3 |
1 | . | 7 | 7 |
The solution is: 1.77
