Maths NCERT Textbooks 6th Class 8th Chapter: Fractions

In the 8th chapter of the 6th grade math textbook, students learn about fractions. Fractions are a way of representing parts of a whole. They consist of two parts: the numerator and the denominator.

• Numerator: The top number in a fraction, which tells you how many parts of the whole the fraction represents.
• Denominator: The bottom number in a fraction, which tells you how many equal parts the whole is divided into.

For example, in the fraction 3/4, the numerator is 3, which means the fraction represents 3 parts of the whole. The denominator is 4, which means the whole is divided into 4 equal parts.

Understanding Fractions

To understand fractions, students learn how to:

1. Compare fractions: To compare fractions, you need to find a common denominator. This is the lowest number that both fractions can be written under. For example, the common denominator of 2/4 and 3/6 is 12.

2. Add and subtract fractions: To add or subtract fractions, you need to have the same denominator. If the denominators are different, you need to find a common denominator. Once you have the same denominator, you can add or subtract the numerators.

3. Multiply and divide fractions: To multiply or divide fractions, you need to multiply or divide the numerators and then divide or multiply the denominators. For example, (2/3) * (3/4) = (2 * 3) / (3 * 4) = 6 / 12 = 1/2.

Fraction Operations

Fraction operations involve various techniques, including:

• Equivalent fractions: These are fractions that represent the same value. For example, 1/2 and 2/4 are equivalent fractions.

• Fraction addition and subtraction: These are operations that involve adding or subtracting fractions with the same denominator. For example, (1/2) + (1/2) = 1/1 = 1.

• Fraction multiplication and division: These are operations that involve multiplying or dividing fractions. For example, (1/2) * (1/3) = 1/6.

Fraction Word Problems

Fraction word problems involve real-life scenarios that require the use of fractions. These problems can be in the form of addition, subtraction, multiplication, or division. For example, "John ate 3/4 of a pizza. His sister ate 1/4 of the same pizza. How much pizza was left?"

Practice Problems

To practice understanding and using fractions, students can work on the following problems:

1. Compare the fractions 1/2 and 3/4.
2. Add the fractions 1/2 + 1/4.
3. Multiply the fractions (1/2) * (1/3).
4. Solve the word problem: John ate 3/4 of a pizza. His sister ate 1/4 of the same pizza. How much pizza was left?

Conclusion

Fractions are an essential concept in mathematics that helps us understand parts of a whole. By learning about fractions, students can solve various problems and understand real-life scenarios. Practicing problems and applying these concepts can help students become more comfortable with fractions and their operations.
