Answers
A number is formed by grouping the digits together.
● Each digit has a fixed position called its place.
● Each digit has a value depending on its place called the place value of the digit.
● The face value of a digit for any place in the given number is the value of the digit itself
● Place value of a digit = (face value of the digit) × (value of the place)
1. The place value of every one-digit number is the same as and equal to its face value.
(i) Place value and face value of 1, 2, 3, 4, 5, 6, 7, 8 and 9 are 1, 2, 3, 4, 5, 6, 7, 8 and 9 respectively.
(ii) The place value of zero (0) is always 0. It may hold any place in a number, its value is always 0.
As, in 105, 350, 42017, 90218 the place value of 0 in each number is 0.
