# Decimals and Place Value

Decimals allow us to write or present numbers that would have a fraction with a denominator of 10 or 10 multiple without the fraction. Place value tells us the mathematical value one digit of a number has to another digit to its left or right.

Moving left each place value position is 10 times greater the position to its right.

Moving right each place value position is 10 times less the position to its left.

Without a decimal a number can never be less than 1 and have value.

Unit position number (1 x)

Tens position number

(10 x unit position)

Hundreds position number

(100 x unit position)

Hundredths position (8/100)

Thousandths position (6/1,000)

With place value and decimals, numbers can be as large or small as needed.
