Question
![**Understanding Decimal Multiplication**
In this example, we are asked to find the product of two decimal numbers:
**3.2 × 2.4**
To solve this multiplication problem, follow these steps:
1. **Ignore the Decimals Initially:** Pretend the numbers are whole numbers (32 and 24) and multiply them as usual:
\[
32 \times 24 = 768
\]
2. **Count Decimal Places:** In the original numbers, there is a total of two decimal places (one in 3.2 and one in 2.4).
3. **Place the Decimal Point:** Move the decimal that many places to the left in your product:
\[
768 \rightarrow 7.68
\]
Therefore, the product of 3.2 and 2.4 is **7.68**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb521bf61-1ddc-4576-b7c2-f1e1a90c06d9%2Fe4053b2b-43be-4542-bb32-472eca700733%2F6t9mm5_processed.jpeg&w=3840&q=75)
