1-0=1
Place value | tens | ones | . | tenths | hundredths | thousandths |
6 | 4 | . | 5 | 2 | 1 | |
- | 1 | . | 4 | 0 | 0 | |
. | 1 |
Subtract the numbers in the hundredths column from the top number:
2-0=2
Place value | tens | ones | . | tenths | hundredths | thousandths |
6 | 4 | . | 5 | 2 | 1 | |
- | 1 | . | 4 | 0 | 0 | |
. | 2 | 1 |
Subtract the numbers in the tenths column from the top number:
5-4=1
Place value | tens | ones | . | tenths | hundredths | thousandths |
6 | 4 | . | 5 | 2 | 1 | |
- | 1 | . | 4 | 0 | 0 | |
. | 1 | 2 | 1 |
Subtract the numbers in the ones column from the top number:
4-1=3
Place value | tens | ones | . | tenths | hundredths | thousandths |
6 | 4 | . | 5 | 2 | 1 | |
- | 1 | . | 4 | 0 | 0 | |
3 | . | 1 | 2 | 1 |
Write 6 in the tens place.
Place value | tens | ones | . | tenths | hundredths | thousandths |
6 | 4 | . | 5 | 2 | 1 | |
- | 1 | . | 4 | 0 | 0 | |
6 | 3 | . | 1 | 2 | 1 |
The solution is: 63.121
