Which number is rational and a real number, but not an integer?

Option: D is the correct answer.

          D.   5/7

We know that a real number is a combination of:

  1) Rational numbers

 2) Irrational numbers

Also, further the rational number is divided into integers and non-integers.

If a number is represented as a whole i.e.   -3, -2,-1,0,1,2,3,

Then such numbers are integers and any number of the form p/q where q≠1 and q does not properly divide p are non-integers but a rational number.

Hence, among following given options the number which is rational and a real number but non-integer is:

          Option: D

( Option: B is an integer

and option: C is an irrational number)
