To perform the subtraction \(1.38 - 0.73\), we can align the numbers by the decimal point:
```
1.38
- 0.73
______
```
Now we can subtract starting from the rightmost digit (the hundredths place):
1. Subtract the hundredths: \(8 - 3 = 5\)
2. Subtract the tenths: \(3 - 7\): Since we can't subtract 7 from 3, we need to borrow 1 from the whole number part. The 1 becomes 0 and the 3 becomes 13.
- Now, \(13 - 7 = 6\)
3. Subtract the whole numbers: \(0 - 0 = 0\), and since we borrowed 1 earlier, it remains 0.
Putting it all together, we have:
```
1.38
- 0.73
______
0.65
```
Thus, \(1.38 - 0.73 = 0.65\).
