Question

If a whole number is less than 100, then it is a _____.

a) Prime number
b) Composite number
c) 2-digit number
d) Odd number

Answer 1

The correct answer is c) a 2-digit number, since any whole number less than 100 must fall in the range of 10 to 99, inclusive.

Step-by-step explanation:

The statement 'If a whole number is less than 100, then it is a _____.' is c) a 2-digit number.

A 2-digit number is any whole number from 10 to 99, which fits the condition of being less than 100. Option a) is incorrect because not all numbers less than 100 are prime; for example, 4 and 10 are not prime but they are less than 100. Option b) is also incorrect because, similarly, not all numbers less than 100 are composite; 1, 2, and 3 are such examples. Lastly, option d) is incorrect because numbers less than 100 can be either odd or even, such as 2 (even) or 3 (odd).

The classification as a 2-digit number is not dependent on the number's divisibility or parity (whether it is odd or even), but strictly on its place value, which denotes its position between 10 and 99.
