Answer:
Rational:-5, 2/3, 0.5, sqrt 16
Irrational: sqrt 11, pi
Step-by-step explanation:
A rational number is a number which can be represented as a ratio or fraction and whose decimal is terminating or repeating. This includes all whole numbers positive and negative too.
Ex. -5, 2/3, 0.5, sqrt 16
An irrational number is a number that CANNOT be represented as a ratio or fraction and whose decimal is NOT terminating or repeating. These often include square roots and numbers like pi.
Ex. sqrt 11, pi
It would be 734.16 because 638.40+15% = 734.16
