Question

use the hundredths to add or subtract
0.47 - 0.21

Answer 1

To perform the subtraction \(0.47 - 0.21\), you can align the numbers by their decimal points:

```
0.47
- 0.21
-------
```

Now subtract the hundredths and the tenths:

1. **Subtract the hundredths**: \(7 - 1 = 6\)
2. **Subtract the tenths**: \(4 - 2 = 2\)

Putting it all together, you get:

```
0.47
- 0.21
-------
0.26
```

So, \(0.47 - 0.21 = 0.26\).
