How to Multiply Numbers with Decimals
This is the third part of the Operations on Decimals Series and in this post, we discuss about Multiplication of Decimals. In multiplying decimals, the decimal point in the product has something to do with the number of decimals of the factors.
How to Multiply Numbers with Decimals Examples
Example 1: What is 
In this example, only one factor has a decimal number, the other is a whole number. To multiply, first, ignore the decimal point and then just multiply the numbers:
After multiplying, count the number of decimal numbers (numbers after on the right hand side of the decimal point) of the factors. There is only one decimal number which is 6. So, in the product, starting from the right, count one number and then place the decimal point before that number making it 
So, the final answer is
Example 2: What is 
Again, ignore the decimal points and multiply the numbers:
There is one decimal number in the first factor and one in the second factor. Therefore, there are two decimal numbers. Now, count two numbers from the right, and place the decimal point before the last number on your count.
Therefore, the correct answer is 
Example 3: What is
Now, 
Multiplying Decimal Numbers by 10
In multiplying decimal numbers by 10 or its powers, just count the number of zeroes and move the decimal point to the right hand side the number of zeroes appear.
Example 1: What is 
Ten has one zero, so, we move the decimal point one place to the right hand side. Therefore, the correct answer is 
Example 2: What is 
There are two zeros, so we move the decimal point two digits to the right hand side. Moving the decimal points gives us
Example 3: What is 
There are three zeros, however, only one decimal point. So, we move the decimal point one time to the right of seven, and add two zeros. Therefore, the final answer is 
In the next post, we will be discussing about division of decimal numbers.
