To solve the problem \( 16.82 - 5.21 \), you can write it vertically like this:
16.82
- 5.21
--------
Now, align the decimal points and subtract from right to left:
- Start from the rightmost column (hundredths): \( 2 - 1 = 1 \)
- Next, for the tenths column: \( 8 - 2 = 6 \)
- For the units (ones) column: \( 6 - 5 = 1 \)
- Lastly, for the tens column: \( 1 - 0 = 1 \) (since there's no tens in 5.21)
Now, putting it all together, we get:
16.82
- 5.21
--------
11.61
So, \( 16.82 - 5.21 = 11.61 \).
