Introduction
Multiplying decimals requires counting decimal places to position the point correctly in your answer.
The Process
Multiply as if there were no decimals, then count total decimal places in both numbers and place the point.
Example
0.3 × 0.2 = 0.06 (3×2=6, total 2 decimal places)
Decimal × Whole Number
Keep the same number of decimal places as the decimal factor.
Example
2.5 × 4 = 10.0 = 10 (one decimal place in 2.5)
Key Takeaways
- 1Multiply ignoring decimals first
- 2Count total decimal places in factors
- 3Place decimal point in product accordingly
