∙ 9y agoThe number 31 (decimal) can be represented as a binary number this way: 11111 ...which is 1 + 2 + 4 + 8 + 16 = 31 Note the number 31 is one less than a power of two. Numbers like that are always strings of 1's for binary digits.
It can!The difference between 31/2 and 31/3, for example, is 1/6 which is less than 1.
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
the result is a number less than the original number
1, 11, 21, 31, 41. 1 is not a prime number.

11, 31, 41, 61, 71
When the number is between 0 and 1, or less than -1
the result is a number less than the original number
1, because 31 is a prime number, and so there will be no number which divides into it other than 31 and 1.
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
