2.015 ( bar on 15 )

SOL.

let : x = 2.015 (bar on 15 ) .......= 2.0151515........(1)
since Two digit is repeating,
therefore we multiply both sides by 100.

100x = 201.01515............(2)

subtract from (2) from (1), we get
100x - x = 201.0151515....- 2.0151515...

99x = 198

x = 198/99

Answer 2

Let x = 2.015 (bar on 15)

==================

Multiply by 10 on both sides,

10× x = 10× 2.015 (bar on 15)

=> 10x = 20.15 bar

----------------------

As there are two (1 and 5) numbers under bar, multiply by 100 on both sides,

=> 100×10x = 100× 20.15 bar

=> 1000x = 2015.15

Then, subtract 10x from both sides,

1000x = 2015.15 bar
-10x = -20.15 bar

x = 1995/990

2.015 bar = 1995/990
