How to Solve Decimal Division with a Missing Number?
FAQs on Class 6 Decimal Division: Find the Missing Dividend or Divisor
1. How do you divide decimals by whole numbers?
To divide a decimal by a whole number, you perform long division as you normally would and place the decimal point in the quotient directly above the decimal point in the dividend. This ensures the decimal place value is maintained correctly in the answer.
- Step 1: Set up the long division problem with the decimal number as the dividend and the whole number as the divisor.
- Step 2: Place the decimal point in the answer space (the quotient) directly above the decimal point in the dividend.
- Step 3: Divide the numbers as you would with whole numbers, ignoring the decimal point for the calculation.
- Step 4: If there is a remainder, add zeros to the end of the dividend and continue dividing until the remainder is zero or you reach the desired precision.
2. What is a missing dividend in decimal division, and how do you find it?
A missing dividend is the unknown number that is being divided in an equation. To find the missing dividend in a decimal division problem, you must use the inverse operation, which is multiplication.
The rule is: Dividend = Divisor × Quotient. For an example like ___ ÷ 4 = 3.5, you would multiply the divisor (4) by the quotient (3.5). The calculation 4 × 3.5 = 14.0 reveals that the missing dividend is 14.0.
3. How do you solve for a missing divisor in a decimal division problem?
To find the missing divisor in a decimal division problem, you need to rearrange the equation and divide the dividend by the quotient. This method is a key part of solving missing number in decimal division exercises.
The rule is: Divisor = Dividend ÷ Quotient. For an example like 8.4 ÷ ___ = 2.1, you would divide the dividend (8.4) by the quotient (2.1). The calculation 8.4 ÷ 2.1 = 4 shows that the missing divisor is 4.
4. What skills will my Class 6 child learn from this decimal division worksheet?
This decimal division Class 6 worksheet helps students master key mathematical skills beyond basic calculation, building a strong foundation for more advanced topics. It focuses on strengthening both procedural fluency and logical reasoning.

- Inverse Operations: Reinforces the connection between division and multiplication.
- Calculation Skills: Improves accuracy and speed in dividing 1- and 2-digit decimals by whole numbers, which is crucial for Class 6 exam prep.
5. How can I teach decimal division to a Class 6 student effectively?
Teaching decimal division to a Class 6 student is most effective when you use a structured, step-by-step approach combined with practical exercises. This worksheet is designed to support that process.
- Review Basics: First, ensure the student has a strong grasp of decimal place value and standard long division.
- Demonstrate Stepwise: Show how to place the decimal point in the quotient before starting to divide. Use a solved example.
- Use Practice Worksheets: A printable decimal worksheet like this one provides focused practice on specific skills, including dividing decimals by 2-digit whole numbers.
- Incorporate Missing Number Problems: These problems encourage critical thinking rather than just rote calculation.
6. Are there any examples of dividing decimals by 2-digit numbers in this worksheet?
Yes, this dividing decimals by whole numbers worksheet includes a variety of problems to ensure comprehensive practice. The questions involve dividing 1- and 2-digit decimals by both single-digit and 2-digit whole numbers.
This variety helps students build confidence and prepares them for different types of questions they might encounter in exams. The included answer key allows for checking work on all problems, including those with larger divisors.
7. Is this decimal division worksheet available as a printable PDF?
Absolutely. This decimal division worksheet PDF is designed to be easily downloaded and printed for free. The printable format is ideal for students who need extra practice at home, for teachers to use in the classroom, or for parents to help with homework and exam revision.
8. Does this worksheet for decimal division have an answer key?
Yes, a complete and accurate answer key is provided with this decimal division worksheet. The inclusion of answers allows students to self-assess their work, understand their mistakes, and correct them independently. This is essential for building confidence and mastering the topic of dividing decimals by whole numbers.
9. What types of questions are included in this missing dividend/divisor worksheet?
This worksheet is structured to build skills progressively through different activities, with a special focus on missing number problems in decimal division.
- Find the Missing Dividend: Questions where the student must calculate the initial number being divided (e.g., ___ ÷ 5 = 1.2).
- Find the Missing Divisor: Problems requiring the student to find the number they are dividing by (e.g., 6.3 ÷ ___ = 3).
- Mixed Decimal Division: Standard division problems to reinforce the core skill and check for overall accuracy.
10. How do missing number problems help in understanding decimal division?
Missing number problems are highly effective because they encourage students to think about division as a concept rather than just a procedure. Instead of just calculating an answer, students must analyze the relationship between the numbers.
By solving for a missing dividend or divisor, students actively use inverse operations (multiplication and division). This strengthens their logical reasoning, deepens their understanding of number properties, and improves their mental maths abilities, making it an excellent preparation tool for Class 6 maths exams.
