Solution - Long subtraction
97.25
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
Place value | hundreds | tens | ones | . | tenths | hundredths |
1 | 3 | 7 | . | 2 | 5 | |
- | 4 | 0 | ||||
. |
Put zeros in the blank number places:
Place value | hundreds | tens | ones | . | tenths | hundredths |
1 | 3 | 7 | . | 2 | 5 | |
- | 4 | 0 | . | 0 | 0 | |
. |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
5-0=5
Place value | hundreds | tens | ones | . | tenths | hundredths |
1 | 3 | 7 | . | 2 | 5 | |
- | 4 | 0 | . | 0 | 0 | |
. | 5 |
Subtract the numbers in the tenths column from the top number:
2-0=2
Place value | hundreds | tens | ones | . | tenths | hundredths |
1 | 3 | 7 | . | 2 | 5 | |
- | 4 | 0 | . | 0 | 0 | |
. | 2 | 5 |
Subtract the numbers in the ones column from the top number:
7-0=7
Place value | hundreds | tens | ones | . | tenths | hundredths |
1 | 3 | 7 | . | 2 | 5 | |
- | 4 | 0 | . | 0 | 0 | |
7 | . | 2 | 5 |
Because the upper digit (3) in the tens 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 (13).
