Final answer:
To create two subsets from set U, we need to classify each number as either rational or irrational. Rational numbers can be expressed as a fraction, while irrational numbers cannot. Subset R consists of rational numbers and subset I consists of irrational numbers.
Step-by-step explanation:
To create two subsets from set U, subset R which is the set of rational numbers and subset I which is the set of irrational numbers, we need to classify each number in the set U as either rational or irrational. Rational numbers are numbers that can be expressed as a fraction, while irrational numbers cannot be expressed as a fraction.
Rational numbers in set U: 0, -7, 3/4, 72, 24, 8, 256
Irrational numbers in set U: 0.83, 289, 227
