How to multiply decimals by powers of 10
Multiply Decimals by Powers of 10 Lesson
Here is the general rule:
The number of places you move the decimal point is equal to the number of zeros in the power of ten.
You always move the decimal point to the right when you are multiplying. Let’s break it down with some examples.
 
Multiplying by 10
The number 10 has one zero. This means you move the decimal point one place to the right.
Example: 2.35×10
Start with the number 2.35
Move the decimal point one place to the right: 23.5
So, 2.35×10=23.5
 
Multiplying by 100
The number 100 has two zeros. This means you move the decimal point two places to the right.
Example: 4.872×100
Start with the number 4.872
Move the decimal point two places to the right: 487.2
So, 4.872×100=487.2
 
Multiplying by 1000
The number 1000 has three zeros. This means you move the decimal point three places to the right.
Example: 0.6×1000
Start with the number 0.6
To move the decimal point three places, you need to add zeros as placeholders. Think of it as 0.600.
Move the decimal point three places to the right: 600.
So, 0.6×1000=600
 
This method works because you’re essentially changing the place value of each digit. When you multiply by 10, the “ones” become “tens,” the “tenths” become “ones,” and so on, which is visually represented by shifting the decimal point.
 

The video gives a clear, step-by-step approach to walk through the process of multiplying decimals by powers of 10.
