Find a rational number and an irrational number between 0.1 and 0.2.
Which option lists a valid (rational, irrational) pair in that interval?

Class 9Rational and Irrational NumbersNumber Systems
  • A(0.15 , 0.150150015000... non-recurring)
  • B(0.15 , 0.1212... recurring)
  • C
  • D(0.05 , 0.25)

Step-by-Step Solution

0.15 is rational and lies between 0.1 and 0.2. 0.150150015000... is non-terminating non-recurring (irrational) and also lies in the interval. The other options either give recurring (rational) second entries or values outside the interval.
Answer: A) (0.15 , 0.150150015000... non-recurring)
