We will learn expressing place value and face value of a digit in any number in International and Indian system.
Place value:
We know how to find out the place value of a digit in any number. Now we will learn how to find the place value of a digit of a number written in the International system or Indian system as usual.
Consider the examples to find the place value in Indian system:
(i) Find the place value of digit 1 and 9 in the number 13,45,792 (Indian system)
The place value of 1 in 13,45,792 (Indian system) is 10,00,000 and the place value of 9 in the number is 90.
(ii) Find the place value of digit 5 and 3 in the number 25,40,31,869 (Indian system)
The place value of 5 in 25,40,31,869 (Indian system) is 5,00,00,000 and the place value of 3 in the number is 30,000.
Consider the examples to find the place value in International system:
(i) Find the place value of digit 7 and 6 in the number 751,607 (International system)
The place value of 7 in 751,607 (International system) is 700,000 and the place value of 6 in the number is 600.
(ii) Find the place value of digit 9 and 4 in the number 954,328,671 (International system)
The place value of 9 in 954,328,671 (International system) is 900,000,000 and the place value of 4 in the number is 4,000,000.
Face value:
As we know that face value of a digit in a number is the digit itself.
Consider the examples to find the face value in International system and Indian system:
(i) Find the face value of digit 8 in the number 820,417,356 (International system).
The face value of 8 in 820,417,356 (International system) is 8
(ii) Find the face value of digit 8 in the number 28,97,31,450 (Indian system).
The face value of 8 in 28,97,31,450 (Indian system) is 8
Therefore, in both the cases the face value of a digit in a number is the digit itself.
