Write the three whole numbers occurring just before 10001
Whole numbers are part of real numbers including all the positive integers and zero, but not the fractions, decimals, or negative numbers
Answer: The three whole numbers before 10001 are 10000, 9999 and 9998
To find the three whole numbers before 10001 we can keep subtracting 1 from it 3 times and write the new number
Explanation:

When we subtract 1 from 10001 we get 10000

Now, subtract 1 from 10000 and we get 9999

Now subtract 1 again from 9999 to get 9998
