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 numbers? What fraction will it be for integers?
-3, -2, -1, 0, 1, 2, 3
There are 7 numbers
As we know Natural numbers start from 1
∴ total natural numbers in the collection = 3 (1, 2, 3)
Hence the fraction will be 
As we know Whole number starts from 0
∴ total whole numbers in the collection = 4 (0, 1, 2, 3, 4, 5)
Hence the fraction will be 
126
