Decimal Place Values : Concept & Chart

In this post we will understand the concept of decimal place value and the meaning of the terms tenth, hundredths ad thousandth.

After the concept we will move on to solve some questions related to decimal place value which are to the standard of Grade 5

Place Value Concept Review

Before learning the decimal place value, let us try to review the concept of place value in whole number.

Consider the whole number 479

The place value of the number can be written as:

Here the digits of 479 are represented as:

From the above image you can observe that:
⟹ Digits in Ones places are represented as it is (here 9)
⟹ Digits in Tens places are represented by multiplication with 10 (here 70)
⟹ Digits in Hundred places are represented by multiplication with 100 (here 400)

Decimal Place Value

Now let us introduce numbers after the decimal point
Let the number be 479.362

From the above image you will observe that:
⟹ Number just after the decimal point is called Tenths place (here 3)
⟹ Second number after the decimal point is called Hundredths place (here 6)
⟹ Third Number after the decimal point is called Thousandth place (here 2)

Let us understand each decimal value in detail

Tenths Place in Decimal

The number just after the decimal point is the Tenth Place.

The simplest tenth place number is 0.1

In fraction form 0.1 is written as \frac{1}{10}

Understanding Tenth Place using illustration

Let whole number 1 is represented by rectangular box

Now \frac{1}{10} is represented as one tenth part of the rectangular box

Let us look at another example of Tenth decimal place

Example 02
0.6 or ( \frac{6}{10} )

If whole number 1 is complete box, then 0.6 or \frac{6}{10} is six tenth part of the given box

Example 03
Representation of number 2.4

2.4 is made up of two numbers
⟹ whole number 2
⟹ decimal number 0.4 (or \frac{6}{10} )

If whole number 1 is represented by complete box, then 2.4 can be shown as follows:

From the above image you can observe that:
⟹ Whole number 2 is represented by 2 rectangular boxes
⟹ decimal 0.4 is represented by four-tenth part of the box

I hope you now have basic understanding of the tenth place of decimal.
Let us now move to understand the hundredth place of decimal

Hundredths Place in Decimal

The second place after decimal is the Hundredths Place value.

The simplest Hundredths Place value is 0.01

In the fraction form 0.01 is written as \frac{1}{100}

Hundredths Place Value using Illustration

Let 1 is represented as complete rectangular box.
Then \frac{1}{100} is one hundredth part of the rectangle

Let us see some other examples for conceptual clarity

Example 2
0.37

Let us write 0.35 in fraction form
0.35 ⟹ \frac{35}{100} \frac{35}{100} represents 35th part of the whole box

Example 03
2.42

The number 2.42 is made of two parts
⟹ whole number 2
⟹ decimal number 0.42 ( or \frac{42}{100} )

The number can be illustrated as follows

In the above image you will observe that:
⟹ whole number 2 is represented by 2 yellow boxes
⟹ 0.42 is represented by third box which is 42/100 part of the box

I hope hundredth place value in decimal is also understood by the students.
Let’s now move on to understand the thousandth place value.

Thousandth Place value in decimal

The third number after the decimal is the thousandth value of the decimal

The simplest thousandth place value is 0.001

The fraction form of 0.001 is \frac{1}{1000}

Understanding Thousandth place using illustration

Let 1 represent the whole cube.
Then \frac{1}{1000} is one thousandth part of rectangle as shown in the image below

In the above image you can see that the cube is divided into thousand parts.
Out of thousand box, only one box is colored in green.
Hence the image represents \frac{1}{1000} part of the cube

Let us look at another example for conceptual clarity

Example 02
0.132

Let us write 0.132 in fraction form
0.132 ⟹ \frac{132}{1000} \\\

If whole number 1 is the complete cube, then \frac{132}{1000} is 132 parts of thousand equal parts.

We are done with conceptual part of decimal place value.
Let us understand the summary of this chapter through decimal place value chart.

Summary of Tenth, Hundredth & Thousandth Place

The right side of decimal point is the start of decimal place value

Tenth Place (1/10) ⟹ Digit just right of decimal
Hundredth Place (1/100) ⟹ 2nd digit after decimal
Thousandth Place (1/1000)⟹ 3rd Digit after decimal

Decimal Place Value Chart

The chart will basically tells the place value of any given number.

The chart is basically divided into three segments
(a) Decimal Point
(b) Integer Values (Left side of decimal point)
(c) Decimal Values (Right side of decimal point)

In order to use the chart, the student should have clear understanding of both whole number place value and decimal number place value.

Below is the chart for your reference

Let us understand the use of the chart with the help of example

Example 01
Find the place value of given number with the help of Place Value Chart
12.365

From the above table you can note that:
1 ⟹ is in Tens Place
2 ⟹ Ones Place
. ⟹ decimal point
3 ⟹ Tenth Place
6 ⟹ Hundredth Place
5 ⟹ Thousandth Place

This is how Place Value chart for numbers.
Let us look at another example for conceptual clarity

Example 02
Find the place value of number
⟹ 362.969

From he above table you can note that
3 ⟹ is in Hundreds Place
6 ⟹ is in Tens Place
2 ⟹ Ones Place
. ⟹ decimal point
9 ⟹ Tenth Place
6 ⟹ Hundredth Place
9 ⟹ Thousandth Place

I hope that the concept of decimal place value is clear.
