Arbitrarily write 5 rational numbers (without repetition), of which 3 are non positive and non negative, and 5 cannot be integers

Arbitrarily write 5 rational numbers (without repetition), of which 3 are non positive and non negative, and 5 cannot be integers

Non positive numbers are negative numbers and 0, and non negative numbers are positive numbers and 0
In the title "three numbers are non positive and non negative", does the Dun sign mean and or? If it is the former, then the three numbers are all 0. The title requires that they cannot be repeated and cannot be integers, so the title is wrong
If it is the latter, it requires that one of the three numbers cannot be a non positive number or a non negative number (in this case, how can it feel that only two numbers have been mentioned), and it is a non repeating fraction (five numbers cannot be integers), then it can be written as - 1 / 2, 1 / 2, 1 / 3, - 1 / 3
To sum up, the title is wrong
