decimal Place valUe and exPanded form

We know that the decimal part of a decimal number is separated from the whole
part by a decimal point. Decimal part follow a place value pattern just as the whole

part of the number. But the decimal place value works from left to right, in just the

reverse manner of the whole number part.
1
The place value of first right of the units place is tenths 10 = 0.1 and the place

value of the hundredths place is 1 = 0.01 .
100

example: Write the place value and expanded form of the following numbers:

(a) 3.5 (b) 8.27

Solution:

(a) Ones • tenths
Get it right!
3 • 5 12.45 – Twelve point
Place Value
5 tenths 5 × 0.1 = 0.5 forty-five 7
3 ones 3 × 1 = 3 12.45 – Twelve point
four five 3
Expanded form: 3.5 = 3 ones + 5 tenths = 3 + 0.5
