Final answer:
Some of the numbers are rational and some are irrational. Rational numbers can be expressed as fractions, while irrational numbers cannot.
Step-by-step explanation:
In this set of numbers, 36, 8, and 3 are rational numbers, while 5.3 and 7 are irrational numbers. A rational number is any number that can be expressed as a fraction, while an irrational number cannot be expressed as a fraction and has an infinite, non-repeating decimal representation. For example, 36 can be written as 36/1, making it a rational number. On the other hand, 5.3 and 7 cannot be written as fractions and have decimal representations that go on forever without repeating, making them irrational numbers.
