A) A rational number that is between 9.5 and 9.7 could be 9.6 because it can be written as a fraction (in this case 9 6/10 or 9 3/5)
B) An irrational number could be the square root of 91 because it's value cannot be written as a fraction, as with all other square roots of non-perfect squares. sqrt(91) is about 9.54 rounded to the nearest hundredth.
Hope this helped!
