To find : which number produces a rational number when added to 0.53

Solution : Now, we add each number one by one

Sum of any rational number with irrational number is always a irrational number

A. irrational number

=3.671393....= irrational number

B. irrational number

=2.766...... = irrational number

C. irrational number

=irrational number

D. rational number

=1.2442857142857142857142857...= rational number  

as repeating numbers are also a rational number

Therefore, A,B,C are irrational number

and D is a rational number

true
