LEVEL-1
EXAMPLE 1 Express each of the following decimals in the form
(i) 0.1
(ii) 0.2
(iii) 03
(iv) 0.4
(v) 0.5
(vi) 0.6
SOLUTION (i) Let x = 0.1. Then,
x = 0.11111...
10x = 1.11111...
On subtracting (i) from (ii), we get
9x = ​
how to solve

Answer 1

Answer:

let x=0.1

then x=0.1111... ———¹

multiply by 10 to both side

10x=1.111 ———²

subtract 2 from 1 we get

10x-x =1.111-0.1111

9x =1

X =1/9
