Question

Write the fraction representing the total number of natural numbers in the collection of numbers -3, -2, -1, 0, 1, 2, 3. What fraction will it be for whole number? What fraction will it be for integers?

Answer 1

Given collection is -3, -2, -1, 0, 1, 2, 3.

Natural numbers are 1, 2, 3, 4, 5, ......
In the given collection the Natural numbers are = 1, 2, 3
$\therefore$ The fraction of natural numbers to the collection =$\frac{3}{7}$

Whole numbers are natural numbers and 0.
Now, whole numbers in the given collection are = 0, 1, 2, 3
The fraction of whole numbers to the collection =$\frac{4}{7}$
Integers in the given collection are = -3, -2, -1, 0, 1, 2, 3
The fraction of integers to the collection = $\frac{7}{7}$ =$\frac{1}{1}$
