Q.3. Express the following in the p/q form where 'p' and 'q' are integers and q≠0.
(i) 0.6(bar on 6)
Solution :
Let x = 0.66666.......................(1)
10x = 6.66666...........................(2)
(2) - (1) = 6.66666..... - 0.66666.....
10x - x = 6
9x = 6
x = 6/9 = 2/3
_________________________
(ii) 0.47(bar on 7)
Let 10x = 4.77777.......................(1)
100x = 47.77777........................(2)
(2) - (1) = 47.77777..... - 4.77777.....
100x - 10x = 43
90x = 43
x = 43/90
_________________________
(iii) 0.001(bar on 001)
Let x = 0.001001.........................(1)
1000x = 1.001001......................(2)
(2) - (1) = 1.001001... - 0.001001...
1000x - x = 1
999x = 1
x = 1/999
