Answer 1

Answer:

(c) 0.2

Step-by-step explanation:

This is because, the place values of digits are in the following order:

H  T  O        ( where H is Hundreds, T is Tens, O is Ones place)

a   b  c          ( a, b, c are constants (simple numbers)

When it comes to decimals, it is

H  T  O . Tenth  Hundredth  Thousandth

a   b  c  .   m              n                    o                ( m, n, o are also simple no.'s)

Here, we observe that 2 is present in tenth place of the place values. So in terms of the options given,

Answer- (C) - 0.2

Answer 2

Given :  1.25

To Find : place value of 2 in 1.25

(a) 1

(b) 2

(c) 0.2

(d) 20​

Solution:

Face Value of a digit always remains same instead of its position in number

Place Value of a number Depends upon its position in number

Place Value of a digit after Decimal = Face Value / 10ⁿ

where n is the position of Digit after Decimal place

Place Value of a digit before Decimal = Face Value x 10ⁿ⁻¹

where n is the position of Digit before Decimal place

1.25  = 1 x 10⁰ + 2/10¹  + 5/10²

                                       1   .     2         5

     Place Value              1         2/10     5/100

     Face  Value               1        2           5    

Place value of 2 in 1.25 is 2/10  = 0.2

option (c) 0.2
