Question 50: Choose the most correct sentence?

A. R=I∪Q

B. I⊂R

C. I∩Q=∅

D. Both A, B, C are correct

Real numbers include rational and irrational numbers, so R=I∪Q from which I⊂RI . can be derived

We have:

– Every rational number is represented by a recurring finite or infinite recurring decimal.

An irrational number is a number that can be written as an infinite non-recurring decimal.

So I∩Q=

So A, B, and C are all correct.
