Final answer:
The correct answer is 'There is no such number' as a number cannot be both irrational and an integer at the same time.
Step-by-step explanation:
The student is asking about the classification of numbers, specifically a number that is irrational, an integer, and a real number all at once. An irrational number is one that cannot be expressed as a ratio of two integers, and it has non-repeating, non-terminating decimal representation. An integer is a whole number, either positive, negative, or zero, that does not include fractions or decimals. A real number is any number that can be found on the number line, including both rationals and irrationals.
Looking at the options provided:
- a. -4/2 is an integer (-2), after simplification, but not irrational.
- b. 0 is an integer and real, but not irrational.
- c. π/4 is irrational and real, but not an integer.
- d. There is no such number is the correct answer because a number cannot be both irrational and an integer at the same time.
Therefore, the correct answer is d. There is no such number because it's not possible for a number to be irrational and an integer simultaneously.
