Question

6) Which number is an irrational number? A) 3.5 B) 36 C) 48 D) 37 100

Answer 1

3.5, 36, 48, and 37,100 are all rational numbers. If you meant to say "37.100", then that would be irrational. However, I think you made a mistake because we don't know what's supposed to be between 37 and 100.
