Subtract:
39.875 from 70.68

Answer

To solve the problem of subtracting 39.875 from 70.68, we will follow these steps:

### Step 1: Align the numbers
First, we need to write the numbers one under the other, aligning the decimal points. Since 70.68 has only two decimal places, we can add a zero to make it 70.680.

```
70.680
- 39.875
```

### Step 2: Subtract the numbers
Now, we will subtract the numbers starting from the rightmost digit (the thousandths place).

1. **Thousandths place**: 0 - 5. We can't subtract 5 from 0, so we need to borrow 1 from the hundredths place. This makes the hundredths place 7 (from 8) and the thousandths place becomes 10. Now, we have:
- 10 - 5 = 5

2. **Hundredths place**: 7 - 7 = 0

3. **Tenths place**: 6 - 8. Again, we can't subtract 8 from 6, so we borrow 1 from the units place. This makes the units place 6 (from 7) and the tenths place becomes 16. Now, we have:
- 16 - 8 = 8

4. **Units place**: 6 - 9. We can't subtract 9 from 6, so we borrow 1 from the tens place. This makes the tens place 6 (from 7) and the units place becomes 16. Now, we have:
- 16 - 9 = 7

5. **Tens place**: 6 - 3 = 3

Putting it all together, we get:
```
70.680
- 39.875
__________
30.805
```

### Final Answer
The result of subtracting 39.875 from 70.68 is **30.805**.
