CBSE Class 7 Maths Chapter 3 Summary

This section offers concise summaries of key decimal concepts, important for CBSE Class 7 Maths Notes Chapter 3. It covers their structure, value, and basic operations. These notes are essential for quick revision.

Introduction to Decimals

A decimal number includes a whole part and a fractional part. A decimal point separates them. In 12.34, '12' is the whole part. The '.34' is the decimal part. This part shows values less than one, expressed as tenths, hundredths, and so on.

Decimal Place Value System

Decimal numbers follow a place value system, similar to whole numbers. After the decimal point, the order reverses.

• Ones: Value 1, Example (in 3.482): 3

• Decimal Point: -, Example: •

• Tenths: Value 1/10, Example: 4

• Hundredths: Value 1/100, Example: 8

• Thousandths: Value 1/1000, Example: 2

Converting Decimals and Fractions

Converting between decimals and fractions is a key skill.

Decimal to Fraction

To convert a decimal to a fraction:

• Count digits after the decimal point.

• Use 10, 100, 1000, etc., as the denominator, based on the count.

• Example: 0.6 = 6/10, 0.75 = 75/100 = 3/4.

Fraction to Decimal

To convert a fraction to a decimal:

• Divide the numerator by the denominator.

• Example: 1/2 = 0.5, 5/8 = 0.625.

Addition and Subtraction of Decimals

Perform these operations with care:

• Align decimal points vertically.

• Add zeros if numbers have unequal decimal places.

• Perform addition or subtraction like with whole numbers.

• Example: ``` 12.450

• 07.305
  -------
  19.755
  ```

Real-Life Contexts of Decimals

Decimals are common in daily life.

• Money: ₹45.50 means 45 rupees and 50 paise.

• Length: 1.5 m means 1 meter and 50 centimeters.

• Weight: 2.75 kg means 2 kg and 750 grams.

• Volume: 1.25 L means 1 litre and 250 ml.
  Decimals express partial quantities easily, useful in shopping or cooking.

Measurement and Decimals

Decimals link directly to measurement units.

• 1 meter = 100 centimeters. So, 1.45 m = 1 m + 45 cm.

• 1 litre = 1000 millilitres. So, 0.75 L = 750 mL.

• 1 kg = 1000 grams. So, 2.25 kg = 2 kg + 250 g.
  Visualizing decimal measurements helps understand values. This is an important part of cbse class 7 maths chapter 3 notes.
