Express in the form of .

Let …… (1)

As there is one digit after decimal which does not have a bar,

So, we multiply (1) by 10 on both sides to get,

…. (i)

Let

Now, … (1)

As decimal is after two digits,

Multiplying both sides of equation (1) by 100, we get,

100y = 15.1515… (2)

Subtracting equation (1) by (2)

100y – y = 15.1515….– 0.1515….

99y = 15

Put this value in (i) to get,
