Understanding Decimal Multiplication
When multiplying decimals:
- Ignore the decimal points initially and multiply the numbers as if they were whole numbers.
- Count the total number of decimal places in all numbers being multiplied.
- 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
