Understanding the Basics of Multiplying Decimals

Multiplying decimals can seem like a daunting task, but with the right approach, it can be a breeze. In this article, we will guide you through the steps to multiply decimals, providing you with a clear understanding of the process and helping you to become more confident in your mathematical abilities.

Step 1: Multiply the Factors without Decimals

To multiply decimals, we first need to multiply the factors without decimals. This means that we will ignore the decimal points and multiply the numbers as if they were whole numbers. Let's take the example given in the problem: $$3.5 \times 0.97$$

We will multiply the factors without decimals: $$35 \times 97 = 3395$$

Step 2: Determine the Number of Decimal Places

Now that we have the product of the factors without decimals, we need to determine the number of decimal places in each factor. The factor 3.5 has 1 decimal place, and the factor 0.97 has 2 decimal places.

Step 3: Place the Decimal Point

To place the decimal point in the product, we need to add the number of decimal places in each factor. In this case, we have 1 decimal place in the factor 3.5 and 2 decimal places in the factor 0.97. We will add these decimal places to get a total of 3 decimal places.

Step 4: Write the Product with the Correct Decimal Point

Now that we have determined the number of decimal places, we can write the product with the correct decimal point. We will place the decimal point 3 places from the right in the product 3395.

The Final Answer

The final answer is: 3.295

Conclusion

Multiplying decimals may seem like a challenging task, but with the right approach, it can be a breeze. By following the steps outlined in this article, you will be able to multiply decimals with confidence. Remember to multiply the factors without decimals, determine the number of decimal places in each factor, place the decimal point, and write the product with the correct decimal point.
