Question

express in the form of p/q and q should not equal to zero. find 1.27 272727

Answer 1

let x be 1.2727....
let 10x be 12.72727...
let 1000x be 1272.7272...
1000x=1272.72
-10 x=-12.72
990x=1260
x=1260/990=14/11

Answer 2

hello there ^_^

1.272727.....can also be written as 1.27 bar

so let assume 1.272727 as x

so not lets take 127.272727 as 100x( as it moves to 2 decimal places so 100x is taken)

ATQ
100x - x = 127.272727 - 1.272727
99x= 126
x=126/99
so in simplified form 126/99 = 42/33 which is again simplified as 14/11

1.272727..... in p/q form where q is not 0 is 14/11

hope this helps =)
