How to Subtract Decimals with Different Decimal Places?
FAQs on Subtracting Decimals of Varying Lengths – Class 6 Maths Worksheet
1. How do you subtract decimals of different lengths?
To subtract decimals of varying lengths, you must first align the numbers correctly. Follow these simple steps for accurate decimal subtraction:
- Align the Decimal Points: Write the numbers one below the other, making sure the decimal points line up vertically.
- Add Zeros: Add trailing zeros to the number with fewer decimal places so that both numbers have the same length after the decimal point.
- Subtract Normally: Perform subtraction from right to left, just as you would with whole numbers, borrowing when necessary.
- Place the Decimal Point: Bring the decimal point straight down into your answer.
2. What is the main rule for subtracting decimals?
The most important rule for subtracting decimals is to align the decimal points of the numbers you are subtracting. This ensures that you are subtracting digits with the same place value (tenths from tenths, hundredths from hundredths, etc.). Forgetting this step is the most common mistake in decimal subtraction problems.
3. Why must we align decimal points when subtracting?
Aligning decimal points is crucial because it correctly lines up the place values of each digit. When the decimal points are aligned, you ensure that you are subtracting ones from ones, tenths from tenths, and so on. This prevents calculation errors and is the foundation of performing decimal operations correctly.
4. How do you borrow while subtracting decimals?
Borrowing, or regrouping, in decimal subtraction works exactly the same way as it does with whole numbers. If a digit in the top number is smaller than the digit below it, you borrow from the digit to its immediate left. This process of subtraction with regrouping is essential for solving problems in this Grade 6 maths practice worksheet.
