Q. Which of the following are natural numbers?Multi-select Choices:(A) 3(B) π(C) −2(D) 9
Definition of natural numbers: Understand the definition of natural numbers. Natural numbers are a subset of the numbers we use for counting and ordering. They include all the positive integers starting from 1. They do not include zero, fractions, decimals, or negative numbers.
Evaluate option (A): Evaluate each option to determine if it is a natural number.(A) 3 is a positive integer and it is used for counting. Therefore, it is a natural number.
Evaluate option (B): Evaluate option (B).(B) 3 is listed again and it is the same as option (A). It is a positive integer and is used for counting. Therefore, it is also a natural number.
Evaluate option (C): Evaluate option (C).(C) There is no number provided in option (C). Since there is no number to evaluate, we cannot consider it as a natural number.
Evaluate option (D): Evaluate option (D).(D) 9 is a positive integer and it is used for counting. Therefore, it is a natural number.
