PLACE VALUE AND FACE VALUE

About "Place value and face value"

"Place value and face value" is the much required stuff for the children who study  math in primary level.

Place value :

Place value of a digit in a number is the digit multiplied by thousand or hundred or whatever place it is situated.

For example,

In 25486, the place value of 5 is = 5x1000 = 5000.

Here, to get the place value of 5, we multiply 5 by 1000. Because 5 is at thousands place.

Face value :

Face value of a digit in a number is the digit itself.

More clearly, face value of a digit always remains same irrespective of the position where it is located.   

For example,

In 25486, the face value of 5 is = 5. 

The difference between place value and face value

The difference between place value and face has been illustrated in the picture given below.

Place value

For better understanding, here  we are going to discuss about place value in detail.

When we look at the picture given below, we can clearly understand place value.

To have better understanding of the picture, let us consider an example.

Find the place value of the digit "5" in the number 25486.

Solution : 

As per the first branch, the location of "5" in 25486 is thousands place.

As per the second branch, the value of "5" in 25486 is 5000.

Finally, the place value of "5" in 25486 is "5000"

Shortcut to find place value

Steps involved in finding place value

Step 1 :

Write the digit for the one you want to find the place value.

(In 2586791, we want to find the place value of "8")

Step 2 :

Count the number of digits which come after the digit for the one you want to find the value. 

(In 2586791, after 8, we have four digits "6791")

Step 3 :

Since there are four digits (6791) after 8, take four zeros after 8. 

Then we get 80000.This is the place value of 8

Problems on "Place value and face value"

Problem 1 :

Find the face value and place value of the underlined digit in the number given below.

253869

Solution :

In the number above, 6 is underlined.

The face value of 6 is the same.

So, the face value of 6 is = 6

To get place value, we have to count the number of digits after 6. There is only one digit after 6. 

So, the place value of 6 is = 60

Problem 2 :

Find the face value and place value of the underlined digit in the number given below.

563472

Solution :

In the number above, 2 is underlined.

The face value of 2 is the same.

So, the face value of 2 is = 2

To get place value, we have to count the number of digits after 2. There is no more digit after 2. 

So, the place value of 2 is = 2

Problem 3 :

Find the place value of "K" in the number given below.           

Given that K = 2x and x = 3.

K78952

Solution :

From the given information, let us find the value of "K".

K = 2x = 2(3) = 6 ------------> K = 6

So, K78952 ------------> 678952

To get place value of "K", we have to count the number of digits after 6. There are five digits after 6. 

Hence, the place value of "K" is  = 600000.

Problem 4 :

Find the place value of "K" in the number given below.  Given that K is the even prime number. 

78K346

Solution :

From the given information, let us find the value of "K".

K = 2  (Because 2 is the only even prime number we have in math)

So, 78K346 ------------> 782346

To get place value of "K", we have to count the number of digits after 2. There are three digits after 2. 

Hence, the place value of "K" is  = 2000.

Problem 5 :

Find the place value of "K" in the number given below.  Given that K is a number which is less than 10 and exactly divisible by both 2 and 3.

32K58

Solution :

From the given information, let us find the value of "K".

K = 6 

(Because 6 is the only number less than 10 and also exactly divisible by both 2 and 3)

So, 32K58 ------------> 32658

To get place value of "K", we have to count the number of digits after 6. There are two digits after 6. 

Hence, the place value of "K" is  = 200.

After having gone through the stuff and example problems on "Place value and face value ", we hope that students would have understood "How to do problems on place value and face value"
