Understanding Decimal Multiplication

When multiplying decimals:

1. Ignore the decimal points initially and multiply the numbers as if they were whole numbers.
2. Count the total number of decimal places in all numbers being multiplied.
3. Place the decimal point in the result, counting from the right according to the total decimal places.

Example:
Multiply 1.25 × 0.4:

• Ignore decimals: 125 × 4 = 500
• Total decimal places: 2 (from 1.25) + 1 (from 0.4) = 3
• Place the decimal: 0.500 → 0.5
