Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | ones | . | tenths | hundredths | thousandths |
5 | , | 9 | |||
- | 4 | , | 1 | 6 | 6 |
, |
Put zeros in the blank number places:
Place value | ones | . | tenths | hundredths | thousandths |
5 | , | 9 | 0 | 0 | |
- | 4 | , | 1 | 6 | 6 |
, |
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 number to the left (90) which becomes (89) and get (10).
Place value | ones | . | tenths | hundredths | thousandths |
8 | 9 | 10 | |||
5 | , | 9 | 0 | 0 | |
- | 4 | , | 1 | 6 | 6 |
, |
Subtract the numbers in the thousandths column from the top number:
10-0-6=4
Place value | ones | . | tenths | hundredths | thousandths |
8 | 9 | 10 | |||
5 | , | 9 | 0 | 0 | |
- | 4 | , | 1 | 6 | 6 |
, | 4 |
Subtract the numbers in the hundredths column from the top number:
9-6=3
Place value | ones | . | tenths | hundredths | thousandths |
8 | 9 | 10 | |||
5 | , | 9 | 0 | 0 | |
- | 4 | , | 1 | 6 | 6 |
, | 3 | 4 |
Subtract the numbers in the tenths column from the top number:
8-1=7
Place value | ones | . | tenths | hundredths | thousandths |
8 | 9 | 10 | |||
5 | , | 9 | 0 | 0 | |
- | 4 | , | 1 | 6 | 6 |
, | 7 | 3 | 4 |
Subtract the numbers in the ones column from the top number:
5-4=1
Place value | ones | . | tenths | hundredths | thousandths |
8 | 9 | 10 | |||
5 | , | 9 | 0 | 0 | |
- | 4 | , | 1 | 6 | 6 |
1 | , | 7 | 3 | 4 |
The solution is: 1,734
