Step-by-Step Guide to Adding Decimals for Grade 6 Students
FAQs on Adding Decimals: Class 6 Maths Worksheet (0 to 3 Digits)
1. What is the rule for adding decimals?
The main rule for adding decimals is to align the decimal points vertically before adding the numbers column by column. This ensures that digits with the same place value are added together correctly.
- First, write the numbers one below the other, making sure the decimal points line up.
- Next, add placeholder zeroes to the end of numbers if they have fewer decimal places.
- Then, add each column starting from the right, just as you would with whole numbers, and carry over when necessary.
- Finally, place the decimal point in the answer directly below the other decimal points.
2. How do you add decimals with different digits?
To add decimals with a different number of digits, you must first align the decimal points and then use zeroes as placeholders to make the decimal parts equal in length. This makes the column-wise addition straightforward.
For example, to solve 24.5 + 3.125:
- Write 24.5 as 24.500 to match the three decimal places in 3.125.
- Align the decimals vertically so that the tenths, hundredths, and thousandths columns line up.
- Add each column from right to left to get the correct sum.
3. How do you add whole numbers and decimals?
To add a whole number and a decimal, you should first convert the whole number into a decimal by placing a decimal point at the end of it. This allows you to align the numbers correctly for addition.
For example, to solve the sum 45 + 6.78:
- Treat the whole number 45 as a decimal by writing it as 45.00.
- Align the decimal points of 45.00 and 6.78 vertically.
- Perform the column-wise decimal addition to find the final answer.
4. What types of decimal addition questions are asked in Class 6?
In Class 6 maths, decimal addition questions are designed to test a student's understanding of place value and calculation skills using various formats. This worksheet covers all common types.
- Vertical Addition Sums: Directly adding numbers with 0 to 3 decimal places (e.g., tenths, hundredths, thousandths).
- Horizontal Sums: Problems written in a line (e.g., 5.1 + 12.034) that require you to first align them correctly.
- Fill in the Blanks: Finding a missing decimal number in an addition equation.
- Decimal Word Problems: Solving real-life scenarios involving money, measurements, or distances that require decimal addition.
5. Why is aligning the decimal point important when adding decimals?
Aligning the decimal point is the most important step in decimal addition because it ensures you are adding digits with the same place value together. Incorrect alignment is a common source of errors in decimal sums.
- Proper alignment guarantees that you add tenths to tenths, hundredths to hundredths, and so on.
- If decimal points are not aligned, you might accidentally add digits from different place value columns, which will lead to a wrong answer.
- It maintains the structural integrity and place value of each number throughout the calculation.
6. How can I use this Class 6 adding decimals worksheet at home?

7. Is this adding decimals worksheet for Class 6 printable?
Yes, this worksheet is specifically designed to be printable and is available as a free downloadable PDF file. The layout is optimized for standard A4 paper, ensuring that all decimal addition problems and instructions are clear and easy to read, making it perfect for students who prefer to practice on paper.
8. Does this decimal addition worksheet include an answer key?
Yes, an answer key with step-by-step solutions is included with this worksheet to help students check their work and understand the correct method. The answer key allows for self-assessment, helping students to identify and correct their mistakes independently and build confidence in solving decimal sums.
9. What skills are built by practicing with this decimal addition worksheet?
This worksheet helps Class 6 students develop several fundamental maths skills that are crucial for more advanced topics. It offers targeted practice for concept reinforcement.
- Understanding of Place Value: Strengthens the concept of tenths, hundredths, and thousandths.
- Calculation Accuracy: Improves the ability to perform addition with regrouping (carrying over).
- Attention to Detail: Emphasises the importance of carefully aligning decimal points.
- Problem-Solving: Applies addition skills to solve various decimal word problems.
10. What is a zero placeholder in decimal addition?
A zero placeholder is a zero that is added to the end of a decimal number to make it have the same number of decimal places as another number in the sum. This does not change the value of the number.
- It helps in correctly aligning columns for vertical addition.
- It reduces errors when adding decimals with a different number of digits (e.g., adding 12.3 and 4.567).
- To solve this sum, you would write 12.3 as 12.300, using two zeroes as placeholders before adding.
