Understanding the Basics of Decimal Multiplication
Before diving into the calculation, let’s revisit the fundamentals of multiplying by decimals. When you multiply a number by a decimal like 0.2, it’s equivalent to multiplying by a fraction (2⁄10) and then dividing by 10. This simplifies the process significantly. Here’s how it works:
- Ignore the decimal: Treat 0.2 as 2.
- Multiply: Calculate 1660 × 2.
- Place the decimal: Since 0.2 has one decimal place, move the decimal point one place to the left in the result.
📌 Note: Always count the decimal places in the multiplier to determine where to place the decimal in the final answer.
Step-by-Step Calculation of 1660 × 0.2
Now, let’s apply the above steps to calculate 1660 times 0.2:
Multiply 1660 by 2:
[ 1660 \times 2 = 3320 ]Place the decimal point:
Since 0.2 has one decimal place, move the decimal point one place to the left in 3320, resulting in 332.0.
Thus, 1660 × 0.2 = 332.
Handy Tips for Quick Math
To make decimal multiplication even easier, consider these tips:
- Use mental math: Break down the multiplication into simpler steps (e.g., 1660 × 2 = 3320).
- Practice regularly: The more you practice, the faster you’ll become at these calculations.
- Leverage technology: Use calculators or apps for quick verification.
Step | Action | Result |
---|---|---|
1 | Multiply 1660 by 2 | 3320 |
