How to Solve Decimal Addition and Subtraction Problems in Grade 6
FAQs on Decimals Addition and Subtraction Practice for Class 6
1. How do you add decimals easily for Class 6?
To add decimals easily, you must align the numbers by their decimal points and then add them just like whole numbers. This Class 6 Maths Decimals worksheet provides practice to master this method.
- Step 1: Write the numbers one below the other, making sure the decimal points are aligned in a single column.
- Step 2: Add placeholder zeros to any empty decimal places to make the numbers have the same length.
- Step 3: Add the columns from right to left, regrouping (carrying over) if necessary.
- Step 4: Place the decimal point in your answer directly below the decimal points in the numbers you added.
2. What are the steps for subtracting decimals in Grade 6?
The key steps for subtracting decimals involve aligning the decimal points, adding zeros if needed, and then subtracting as you would with whole numbers. Following these steps ensures accuracy in your calculations.
- Align Decimals: Place the numbers in a column so that the decimal points line up perfectly.
- Add Zeros: If one number has fewer decimal places, add zeros to the end so both numbers have the same length. This is crucial for subtracting decimals from whole numbers.
- Subtract: Starting from the rightmost digit, subtract each column, borrowing from the left when needed.
- Place Decimal Point: Put the decimal point in the final answer directly beneath the other decimal points.
3. Why do we align decimal points when adding or subtracting?
Aligning decimal points is essential because it ensures you are adding or subtracting digits with the same decimal place value. This prevents common calculation errors and is a fundamental rule in decimal operations.
- When you align the points, you are correctly lining up the tenths with tenths, hundredths with hundredths, and so on.
- This is similar to how you align ones, tens, and hundreds places when working with whole numbers.
- Failing to align them would be like adding 10 to 1 instead of 10 to 1.0, leading to an incorrect sum.
