A={-8, 2, 4, 1/2, -7.333...(3s repeat), 5p}
From the set above which are:
A. Natural numbers {2, 4}
B. Rational numbers {-8, 2, 4 1/2, -7.333...(3's repeat}
C. integers {-8, 2, 4}
D. Irrational numbers {5p}
E. Real numbers {-8, 2, 4, 1/2, -7.333...(3s repeat), 5p}
Natural numbers = {1,2,3,...}
Whole numbers = {0,1,2,3,...}
Rational numbers = {positive, negative, or zero integers, fractions with
numerator and denominator integers,
terminating and repeating decimals}
Integers {...-3, -3, -1, 0, 1, 2, 3,...}
Irrational numbers {non-repeating non-terminating decimals}
