Multiplying Decimals: 0.8 x 0.2
Multiplying decimals can seem tricky, but it's actually quite straightforward once you understand the concept. Let's break down how to calculate 0.8 x 0.2.
Understanding the Process
- Ignore the decimal points: Treat 0.8 and 0.2 as whole numbers, so you're essentially multiplying 8 and 2.
- Multiply the whole numbers: 8 x 2 = 16
- Count the decimal places: In the original numbers (0.8 and 0.2), there's one decimal place in each. This means you have a total of two decimal places.
- Place the decimal: Starting from the right side of the product (16), move the decimal two places to the left. This gives you 0.16.
Therefore, 0.8 x 0.2 = 0.16
Visualizing Multiplication
You can also visualize this multiplication as finding the area of a rectangle. Imagine a rectangle with a length of 0.8 units and a width of 0.2 units. The area of the rectangle would be 0.8 x 0.2 = 0.16 square units.
Key Takeaways
- Multiplying decimals is similar to multiplying whole numbers, just with an extra step for placing the decimal.
- Count the total number of decimal places in the original numbers.
- Move the decimal in the product that many places to the left.
