What number produces a rational number when added to 0.53

A number which can be written in the form of , q≠0 , is called a rational number.There are two kinds of rational number

(a)Terminating Decimal--0.5,0.25,0.225,

(b)Non Terminating Repeating Decimal--0.55555555...., 0.658658658......

is a rational number.

So, you can add any decimal to 0.53, such that after adding the number , the resulting number either terminates or it should be Non Terminating Repeating Decimal.

For example: →0.53 +0.10=0.63

→ 0.53 +0.00535353......=0.53535353.......
