Question

find the value of 0.9 bar​

Answer 1

Let x = 0.9999eq 1

here the periodicity is 1

so multiply eq 1 with 10 on both sides

10 × X = 10 × 0.9999.

10X = 09.999 eq 2

subtract eq 1 from eq 2

10X = 09.999

- X = 0.999

_________________

9X = 9

_________________

X = 9/9

X = 1/1

therefore p/q form of 0.9 bar is 1/1

the value of 0.9 bar is 0.999999 continuing like this
