To solve the problem of , we will perform the following steps, ensuring clarity in how decimal subtraction operates:
Step 1: Align the numbers by their decimal points:
0.98
- 0.36
------
Step 2: Subtract from the rightmost column (hundredths place):
We have 8 minus 6 in the hundredths place, which gives us 2.
Step 3: Move to the tenths place:
In the tenths place, we subtract 3 from 9, which gives us 6.
Step 4: Since there is no borrowing across the decimal, move to the units place. Nothing to subtract from left of the decimals, 0 remains unaffected.
0.98
- 0.36
------
0.62
Therefore, the final result of the subtraction is .
0.62
Choose the correct writing form:
Lining up decimal points ensures you're subtracting the same place values - tenths from tenths, hundredths from hundredths. Without proper alignment, you'll get the wrong answer!
Add zeros as placeholders! For example, if subtracting 0.5 - 0.36, write it as 0.50 - 0.36 so both have the same number of decimal places.
Yes, borrowing works the same way! If you can't subtract in a column (like 3-8), borrow from the next column to the left, just like with whole numbers.
Use addition to check! Add your answer to the number you subtracted. If you get the original number, your subtraction is correct: ✓
The decimal point matters! 0.62 means 62 hundredths (less than 1), while 62 means sixty-two whole units. Always include the decimal point in your answer.
