Question

express 0.123bar on 23 as a rational number​

Answer 1

Answer:

Step-by-step explanation:

Let x = 0.123232323....

[Multiply by 10 both sides ]

10x = 1.232323232.....     -(i)

[Multiply by 100 both sides ]

1000x = 123.232323......   -(ii)

subtract (i) from (ii)

we  get,

990x = 122

x = 122/990

x = 61/495

Answer 2

Answer:

61/495

Step-by-step explanation:

let x = 0.123   ( can't make bar so underlining it )

100x = 12.323

subtracting both equations,

100x-x = 12.323-0.123

99x = 12.2

x = 12.2/99 (multiplied numerator and denominator by 10 to remove decimal)

x= 122/990

x= 61/495 (divided by 2)
