Question

13. It is given that H= {x : x is a rational number}, and I = {x : x is an integer). Is ICH? Explain. -​

Answer 1

Answer:

I ⊂ H, because all integers are rational numbers.  Rational numbers include all natural, whole and integer numbers.

Step-by-step explanation:

Let us view the subsets of numbers.

N ⊂ W ⊂ I ⊂ R ⊂ Irrational Numbers.

I ⊂ H, because all integers are rational numbers.  Rational numbers include all natural, whole and integer numbers.

Therefore, all members of I will be a member of R.
