**What are the 6 sets of numbers?**

Types of numbers

- Natural Numbers (N), (also called positive integers, counting numbers, or natural numbers); They are the numbers {1, 2, 3, 4, 5, …}
- Whole Numbers (W).
- Integers (Z).
- Rational numbers (Q).
- Real numbers (R), (also called measuring numbers or measurement numbers).

**What is are the common number set?**

The whole numbers, {1,2,3,…} negative whole numbers {…, -3,-2,-1} and zero {0}. So the set is {…, -3, -2, -1, 0, 1, 2, 3.}

### What number sets does 3 belong to?

## What set of numbers does 3/5 belong to?

rational number

Explanation: Integers are whole numbers. 35 is a rational number because it represents a ratio of two integers (and denominator ≠0 ).

## What is set number?

A set of numbers is really just a group of numbers. You can use the number line to deal with four important sets of numbers: Counting numbers (also called natural numbers): The set of numbers beginning 1, 2, 3, 4 . . . and going on infinitely. Integers: The set of counting numbers, zero, and negative counting numbers.
