Decimal number are:

• "Decimal number" is often used to mean a number that uses a decimal point followed by digits that show a value smaller than one.

Decimal Number's Place value

When we write numbers, the position (or "place") of each digit

is important.

Revisiting Place Value concept

• the "7" is in the Ones position, meaning 7 ones (which is 7),

• the "2" is in the Tens position meaning 2 tens (which is twenty),

• and the "3" is in the Hundreds position, meaning 3 hundreds.

As we move left, each position is 10 times bigger! Tens are 10 times bigger than Ones Hundreds are 10 times bigger than Tens... and ... so on

As we move right, each position is 10 times smaller. From Hundreds, to Tens, to Ones 

But what if we continue past Ones?What is 10 times smaller than Ones?

 $\frac{1}{10}$  i.e . 1 (Tenths) are! 

But we must first put a decimal point,so we know exactly where the Ones position is:

Multiple Choice

Where is the Decimal point in the given Image?

• After 2

• After 4

• After 7

• Before 2

So this number will be called "three hundred twenty seven and four tenths"but we usually just say "three hundred twenty seven point four"

And that is a Decimal Number!

Let's do some more examples
