Proving 0.999....♾ = 1

[Seven]

Proving 0.999....♾ = 1
not around or round figure
but equal to

so ,

let x = 0.999....♾ - eq 1

(then multiply both sides by 10)

so 10x = 9.999....♾ - eq 2

(now subtract eq 1 from eq 2 )

10x = 9.999....♾

- 1x = 0.999....♾
__________________

9x = 9....♾

so x = 9....♾/9

which is equal to 1....♾

, hence proved

● also this eq will only work if there is ♾(infinite) to it , if not it won't work example -

let x = 0.999 - eq 1

multiply both sides by 10

10x = 9.99 - eq 2

now subtract eq 1 from eq 2

so 10x = 9.99

- 1x = 0.999
______________

9x = 8.991

● so it only works when there is infinite to it
