Question

Answer number 9. Remember R stands for real numbers. N for natural numbers. W for whole numbers. Z for integers. Q for rational numbers. I for irrational numbers.
Also please answer all parts of the question.

Answer 1

A = ( R, N, W, Z)

B = ( R, N, W, Z)

C = ( R, N, W, Z, Q, I)

D = (R, I)

How to determine the numbers

Given that;

• R stands for real numbers
• N for natural numbers.
• W for whole numbers
• Z for integers.
• Q for rational numbers
• I for irrational numbers

Real numbers: Real numbers are numbers that are both rational and irrational numbers

Natural numbers: Natural numbers includes all the positive integers from 1 till infinity

Whole numbers: Whole numbers are integers

Integers: Integers are whole numbers that are either positive, negative or zero

Irrational numbers: Real numbers that are not rational

Rational numbers: Rational numbers are numbers in form of  quotients  of integers

For A:

A = ( 4, 6, 8, 10, 12 , 14)

A = ( R, N, W, Z)

For B

B = ( -5, 7, 12, 15, 22)

B = ( R, N, W, Z)

For C

C = ( -3/4, 2/ 3, 1/ 5, 9, 20)

C = ( R, N, W, Z, Q, I)

For D

D = ( -√5, √6, √8, √11)

D = (R, I)
