How to Divide 2-Digit Decimals by a Whole Number Step by Step
FAQs on Dividing Decimals by Whole Numbers: Class 5 Practice Worksheet
1. How do you divide decimals by whole numbers for Grade 5?
To divide a decimal by a whole number, you perform division as you normally would and simply place the decimal point in the answer directly above its position in the number being divided. This method ensures the place value is correctly maintained in the quotient.
- Step 1: Set up the division problem with the decimal number as the dividend and the whole number as the divisor.
- Step 2: Ignore the decimal point for a moment and start dividing from left to right, just like with whole numbers.
- Step 3: Place the decimal point in your answer (the quotient) directly above the decimal point in the dividend.
- Step 4: Continue the division process until you have no remainder or have reached the desired number of decimal places.
2. What are the main rules for dividing decimals?
The most important rule when dividing a decimal by a whole number is to correctly position the decimal point in the quotient. Following this rule ensures your answer is accurate.
- Align the Decimal: The decimal point in the answer must be placed exactly above the decimal point in the dividend.
- Divide Normally: Carry out the long division process as if you were working with whole numbers.
- Use Placeholders: Add zeros to the right of the decimal in the dividend if needed to continue dividing without a remainder.
- Check Your Work: Multiply your quotient by the divisor to see if you get the original dividend.
3. How does this Class 5 worksheet help with dividing 2-digit decimals by a whole number?

4. What are some common mistakes students make in decimal division?
Students often make small errors in decimal division, most commonly related to placing the decimal point or basic calculation. Being aware of these helps in avoiding them.
- Misplacing the Decimal Point: Forgetting to place the decimal in the quotient or putting it in the wrong position.
- Forgetting Placeholders: Not adding a zero in the quotient when a number cannot be divided (e.g., in 6.09 ÷ 3).
- Basic Calculation Errors: Simple mistakes in subtraction or multiplication during the long division process.
- Ignoring Remainders: Stopping the division process too early when a zero could be added to the dividend to continue.
5. Is this dividing decimals worksheet printable and available as a PDF?
Yes, this Class 5 Maths worksheet is designed to be easily accessible and user-friendly. You can download the free PDF file and print it for classroom activities, homework, or extra practice at home. Its format is optimised for standard A4 printing.
6. Why is it important for Grade 5 students to learn decimal division?
Learning decimal division in Grade 5 is crucial as it builds a strong foundation for more advanced mathematical concepts and has many practical uses. It is a fundamental skill for everyday life.
- Real-World Application: It is essential for tasks involving money (e.g., splitting a bill), measurement (e.g., calculating average length), and cooking (e.g., adjusting recipes).
- Foundation for Higher Maths: It is a prerequisite for understanding topics like percentages, ratios, and algebra in higher grades.
- Develops Problem-Solving Skills: Working through decimal division word problems enhances logical thinking and analytical abilities.
7. Can I get the answers for the problems in this worksheet?
Absolutely. This decimal division worksheet comes with a complete answer key that includes detailed, step-by-step solutions for all the problems. This allows students to self-check their work, understand where they went wrong, and learn the correct method for solving each question.
8. How can you divide a decimal by a 2-digit whole number?
The process for dividing a decimal by a 2-digit whole number is the same as dividing by a single-digit number, but it requires more careful calculation. The key is to manage the long division steps accurately.
- Example: To solve 8.55 ÷ 15, you would set up the long division.
- Place the decimal point in the quotient directly above the one in 8.55.
- Determine how many times 15 goes into 85 (5 times), write 5 in the quotient.
- Subtract (85 - 75 = 10), bring down the next digit (5), making it 105.
- Determine how many times 15 goes into 105 (7 times), write 7 in the quotient.
- The final answer is 0.57.
9. What kind of questions are included in this Grade 5 Maths practice worksheet?
This worksheet offers a comprehensive mix of questions to ensure a thorough understanding of dividing decimals. The variety helps cater to different learning styles and builds both conceptual and application skills.
- Calculation Drills: Direct problems like '9.24 ÷ 4' to build fluency.
- Fill-in-the-Blanks: Exercises to reinforce understanding of quotients and divisors.
- Word Problems: Real-life scenarios involving money, distance, and weight to test application skills.
- Visual Models: May include image-based questions using decimal grids to provide a visual representation of division.
10. What is the first step when dividing a decimal like 4.56 by a whole number like 2?
The very first step when dividing a decimal like 4.56 by a whole number like 2 is to correctly set up the long division problem. You place the dividend (4.56) inside the division bracket and the divisor (2) outside. After setting it up, your immediate next action is to place the decimal point in the quotient area, directly above the decimal point in 4.56, before you even begin dividing.
