Explanation

Two thirds is a fraction, so it is rational, and 9.26 is a terminating decimal, so it is rational too. The sum of two rational numbers is rational, making “two thirds plus 9.26” the correct choice. The other choices involve pi or the square root of a non-perfect square, which are irrational.
