Decimal multiplication can seem daunting at first, but with a solid understanding of the fundamentals and a step-by-step approach, you can master it in no time. In this comprehensive guide, we’ll cover everything you need to know about decimal multiplication. Let’s dive in!

What is Decimal Multiplication?

Decimal multiplication is the process of multiplying numbers that have decimal points. It involves multiplying the whole numbers and the decimal parts separately and then adding the results together to obtain the final product.

Step-by-Step Guide to Decimal Multiplication

  1. Align the numbers vertically, placing the decimal points in line.
  2. Multiply the whole numbers as you would with regular multiplication.
  3. Count the total number of decimal places in both numbers.
  4. Ignore the decimal points and multiply the numbers as if they were whole numbers.
  5. Place the decimal point in the product by counting the total number of decimal places from step 3.
  6. Rewrite the product with the decimal point in the correct position.
  7. Include any leading zeros before the decimal point, if necessary.
