How to Subtract Fractions with Different Denominators (Step-by-Step)
FAQs on Subtracting Unlike Fractions – Grade 6 Maths Practice Worksheet
1. How do you subtract fractions with different denominators?
To subtract fractions with different denominators, you must first convert them into like fractions by finding a common denominator. The steps are as follows:
- Find the Least Common Denominator (LCD) of the two fractions. This is the LCM of the denominators.
- Convert each fraction into an equivalent fraction with the LCD as the new denominator.
- Subtract the numerators of the new fractions. The denominator will remain the same.
- Simplify the result to its lowest terms if necessary.
This method is essential for solving subtracting unlike fractions problems in Class 6 Maths.
2. What is the easiest way to find common denominators?
The easiest and most efficient way to find a common denominator is by calculating the Least Common Multiple (LCM) of the denominators. For example, to subtract 1/6 from 1/4, you would find the LCM of 6 and 4, which is 12. This becomes your least common denominator (LCD), ensuring you work with the smallest possible numbers for easier calculations.
3. Is this Grade 6 fractions worksheet printable and free to download?
Yes, this Class 6 Maths worksheet on subtracting fractions is completely free to download and is designed in a print-friendly PDF format. This makes it easy for parents and teachers to print for classroom activities, homework assignments, or at-home revision.
4. Does this worksheet include an answer key?
Yes, a comprehensive answer key is included with this fractions worksheet for Class 6. The solutions are provided to help students check their answers, understand the correct method for subtracting unlike fractions, and learn from their mistakes independently.
5. What skills will my child build with this subtracting unlike fractions worksheet?
This worksheet helps students build several crucial maths skills for Grade 6. By completing the exercises, your child will learn to:
- Find the Least Common Denominator (LCD) for numbers up to 30.
- Convert unlike fractions into equivalent fractions.
- Perform subtraction of numerators accurately.
- Simplify fractions and reduce them to their lowest terms.
These skills are fundamental for mastering fraction subtraction practice.
6. What are examples of unlike fractions subtraction?
An example of subtracting unlike fractions is a problem like 5/8 - 1/4. Here, the denominators (8 and 4) are different. To solve it, you find the common denominator (8), convert 1/4 to 2/8, and then subtract the numerators: 5/8 - 2/8 = 3/8. This worksheet provides many such fraction subtraction questions for practice.
7. Is this worksheet suitable for CBSE and NCERT Class 6 students?
Absolutely. This worksheet for subtracting fractions Class 6 is designed based on the NCERT curriculum and is perfectly aligned with the syllabus followed by CBSE schools. It serves as an excellent resource for exam preparation and concept reinforcement.
8. What types of problems are included in this worksheet?
This worksheet offers a variety of problems to ensure thorough practice on subtracting unlike fractions. The activities include:
- Direct subtraction problems to build core skills.
- Fill-in-the-blank questions to test understanding.
- Column subtraction problems for structured practice.
- Word problems to apply concepts to real-world scenarios.
9. Why is practice important for fraction subtraction?
Consistent practice is crucial because subtracting unlike fractions is a multi-step process that requires accuracy. Regular practice helps students to:
- Quickly identify the LCM for denominators.
- Avoid common errors in converting fractions.
- Build speed and confidence in simplifying answers.
- Strengthen their overall foundation in fractions for more advanced topics.
10. What are 'unlike fractions'?
Unlike fractions are fractions that have different denominators. For example, 1/3 and 3/4 are unlike fractions because their denominators (3 and 4) are not the same. Before you can add or subtract them, you must find a common denominator.
