Answer 1

D is the answer.

It is rational because it can be expressed as a ratio of 2 integers. All rational numbers are real. It is not an integer because it is not a whole number or the ngative of one. It is a fraction.

Answer 2

Option: D is the correct answer.

D. 5/7

Explanation:

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)
