Question

Choose the number that fits into all the following number sets: natural number, whole number, integer.

8

5.3

π

− 3/5

Answer 1

The number that fits into all the following number sets: natural number, whole number, and integer is **8**.

Here's a breakdown of why:

- **Natural Numbers**: These are the positive integers (1, 2, 3, ...). The number 8 is a natural number.
- **Whole Numbers**: These include all natural numbers as well as zero (0, 1, 2, 3, ...). The number 8 is also a whole number.
- **Integers**: These include positive whole numbers, negative whole numbers, and zero (..., -3, -2, -1, 0, 1, 2, 3, ...). The number 8 is an integer.

The other options do not fit into all three sets:

- **5.3**: Not a natural number, whole number, or integer (it is a decimal).
- **π**: Not a natural number, whole number, or integer (it is an irrational number).
- **−3/5**: Not a natural number, whole number, or integer (it is a negative rational number).

Thus, the answer is **8**.
