To perform the subtraction \( 3.3 - 1.27 \), it's beneficial to align the numbers correctly.
First, we can write \( 3.3 \) as \( 3.30 \) for clarity:
3.30
- 1.27
Now, perform the subtraction:
3.30
- 1.27
------
Subtracting from right to left:
- In the hundredths place: \( 0 - 7 \) cannot be done, so we borrow 1 from the tenths (turning 3 into 2), making the hundredths \( 10 - 7 = 3 \).
- Now in the tenths place: \( 2 - 2 = 0 \).
- In the units place: \( 3 - 1 = 2 \).
Combining these, we get:
2.03
Therefore, \( 3.3 - 1.27 = 2.03 \).
If you were asking whether or not you need to add something to the result, no addition is necessary as the calculation is complete, and the result is \( 2.03 \).
