Answer 1

plz mark as brainliest
Let x = 0.171717171717......
Therefore,
100x = 17.1717171717.......     - x=   0.1717171717......_________________________99 x  = 17.0000000000.....
or , x = 17/99
Answer = 0.17171717... in p/q form is 17/99

Answer 2

x=0.177777777777...............i
multiplying equation i with 10,
10x=1.7777777777......................ii
again multiplying equation i with 100,
100x=17.777777....................iii

now subtracting equation ii from iii
100x-10x=17-1
90x =16
x=16/90
x=8/45(p/q form )
