✨ Place Values in Decimal Numbers

🔹 What are Decimal Numbers?

• Decimal numbers are numbers that have a dot (.) called a decimal point.
  Example: 3.45, 12.7, 0.89

📍 Decimal Point

• The decimal point separates:
  ✅ Whole number part (left side)
  ✅ Decimal part (right side)

Example:
7.32 → 7 = whole part, 32 = decimal part

🔵 Place Values After Decimal Point

Each place becomes 10 times smaller as we move right ➡️

Place Value	Name	Fraction Form	Example
1st place after decimal	Tenths (₁⁄₁₀)	0.1 = 1/10	5.3 → 3 is tenths
2nd place after decimal	Hundredths (₁⁄₁₀₀)	0.01 = 1/100	5.38 → 8 is hundredths
3rd place after decimal	Thousandths (₁⁄₁₀₀₀)	0.001 = 1/1000	5.386 → 6 is thousandths

🧮 Examples

✅ Example 1:

4.56

• 4 = Ones
• 5 = Tenths
• 6 = Hundredths

✅ Example 2:

12.307

• 1 = Tens
• 2 = Ones
• 3 = Tenths
• 0 = Hundredths
• 7 = Thousandths

🚦 Key Rules to Remember

🔸 Digits to the right of the decimal point show small parts of a whole
🔸 Each step to the right ÷ 10
🔸 Each step to the left × 10
🔸 Zero (0) in decimals has value depending on the place
Example:
0.40 ≠ 0.004
