Find two rational numbers between 0.1 and 0.2?

A number which can be written in the form of p/q, here p and q are integers and q is not equal is zero is called a Rational number.

Between any two given rational numbers there exist uncountable rational numbers.

So,

0.1 can also be written as,

0.2 can be written as,

So, let's multiply and with to make it easy finding rational numbers between them.

Two rational numbers between and are –

Therefore,

Two numbers between 0.1 and 0.2 are and
