Intro
Learn to multiply decimals by whole numbers with our worksheet, practicing decimal multiplication, whole number operations, and math fluency exercises.
Multiplying decimals by whole numbers is a fundamental mathematical operation that is used in various aspects of life, including science, engineering, and finance. It is essential to understand the concept of multiplying decimals by whole numbers to perform calculations accurately. In this article, we will delve into the world of multiplying decimals by whole numbers and provide a comprehensive guide on how to perform this operation.
To begin with, let's understand the basics of decimals and whole numbers. Decimals are numbers that have a fractional part, which is represented by a dot (.) followed by one or more digits. Whole numbers, on the other hand, are numbers that do not have a fractional part. Examples of decimals include 0.5, 2.7, and 1.9, while examples of whole numbers include 1, 2, and 3.
Multiplying decimals by whole numbers involves multiplying the decimal number by the whole number, just like you would multiply two whole numbers. The main difference is that you need to consider the decimal point when multiplying decimals by whole numbers. To multiply a decimal by a whole number, you can simply multiply the decimal number by the whole number, ignoring the decimal point. Then, count the number of digits to the right of the decimal point in the original decimal number and place the decimal point in the product accordingly.
Multiplying Decimals By Whole Numbers
For example, let's say you want to multiply 2.7 by 3. To do this, you would multiply 27 (the decimal number without the decimal point) by 3, which gives you 81. Then, you would place the decimal point in the product by counting the number of digits to the right of the decimal point in the original decimal number. In this case, there is one digit to the right of the decimal point, so you would place the decimal point one digit from the right in the product, resulting in 8.1.
Steps to Multiply Decimals By Whole Numbers
To multiply decimals by whole numbers, follow these steps: * Multiply the decimal number by the whole number, ignoring the decimal point. * Count the number of digits to the right of the decimal point in the original decimal number. * Place the decimal point in the product by counting the same number of digits from the right.Benefits of Multiplying Decimals By Whole Numbers
