Which is the smallest positive number?
The smallest positive whole number is 1. If you include numbers that aren't whole, then there's no such thing as the 'smallest' one. Whatever number you name, no matter how small it is, I can always name another one that smaller than yours but still positive. For example: Your number . . . 0.000000000000001 My number. . . . . 0.0000000000000001
Are decimals integers?
No. An integer is a whole number such as 2, 10, or 12. A decimal is, as its name suggests, not a "whole" number. It's a number and a supplementary fraction or value.
Is 55 composite or prime?
55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite
Is undecillion a number?
