How to Subtract Decimals Step by Step for Grade 5 Students
FAQs on Class 5 Maths: Subtracting Decimals Digit Practice Worksheet
1. What are the steps to subtract decimals for Class 5?
To correctly subtract decimals, you must line up the decimal points, subtract each column from right to left, and place the decimal point in the final answer.
- Line up the numbers vertically, ensuring the decimal points are aligned.
- If needed, add placeholder zeros to the end of a number so both have the same number of decimal places.
- Subtract the digits in each column, starting from the far right.
- Regroup (or borrow) from the column to the left if the top digit is smaller than the bottom digit.
- Place the decimal point in your answer directly below the decimal points in the problem.
2. Why is it important to line up decimal points when subtracting?
Lining up decimal points is the most important step because it ensures you subtract digits that have the same place value.
By aligning the points, you are correctly subtracting tenths from tenths and hundredths from hundredths. Misaligning the points would be like subtracting ones from tens, which would lead to a completely incorrect answer. This rule is fundamental for accuracy in all decimal subtraction for Grade 5 problems.
3. How do you subtract decimals with a different number of digits?
To subtract decimals with a different number of digits, you must first add placeholder zeros to the number with fewer decimal places to make them equal in length.
- For example, in the problem 23.5 - 8.42, the number 23.5 has one decimal place, while 8.42 has two.
- You add a zero to 23.5 to make it 23.50. This does not change its value.
- Now you can perform the column subtraction: 23.50 - 8.42.
- This technique is essential for correctly subtracting unlike decimals.
4. What is regrouping in a decimal subtraction problem?
Regrouping in decimal subtraction, also known as borrowing, is the process of taking value from a higher place value column and moving it to a lower one.
This is necessary when a digit you are subtracting is larger than the digit you are subtracting from. For example, if you need to subtract 8 hundredths from 2 hundredths, you would regroup 1 tenth (which is 10 hundredths) from the tenths column. This is a key skill for solving more complex decimal subtraction problems.
5. Are there free PDFs for Class 5 decimal subtraction practice?
Yes, this Class 5 Maths Subtracting Decimals Digit worksheet is available as a free, print-friendly PDF that you can download instantly.

9. What age group is this subtracting decimals worksheet best for?
This worksheet is specifically designed for Grade 5 students, who are typically between 9 and 11 years old.
The content, difficulty level, and presentation—including age-appropriate fonts and ample white space—are all tailored to meet the learning needs and curriculum standards for this age group. It is an ideal tool for reinforcing Class 5 Maths concepts related to decimals.
10. How do visual aids like decimal grids help in learning subtraction?
Visual aids like decimal grids and number lines help make the abstract concept of decimal subtraction more concrete and easier for students to understand.
- A decimal grid (a 10x10 square) allows students to physically see a whole, tenths, and hundredths. They can shade a decimal amount and then cross out the part being subtracted to find the answer visually.
- A number line helps students see subtraction as 'counting back' from a certain point.
- These visual aids are particularly effective for visual learners and for building a strong foundational understanding of decimal operations.
