Hi ,
Difinition:
A number which can be written in the form of p / q ,
where p , q are integers and q is not equals to zero
is called a Rational number.
All rational numbers can be converted into decimal
numbers. There are 2 types of decimals
1) Terminating decimals
2) Non - terminating repeating decimals.
Now given number is 2.4 is terminating decimal.
2.4 = 2.4/1 × 10 /10 = 24 /10 = (2 × 12 ) / ( 2 × 5 ) = 12 / 5
Therefore ,
2.4 = 12 / 5 it is in p / q form.
and 12 , 5 are integers.
2.4 = 12/ 5 is a rational number.
I hope this will useful to you.
