Answer:
2 is the smallest number.
Explanation:
2 is the smallest number because, if you will see all these numbers, they are in decimal and after decimal more values are given which is not equal to zero it is greater than zero. If you will convert the number 2 into decimal it will become 2.0, now here also after decimal more value is given but, it is equal to zero not greater than zero, if there were more zero then also its value will 2 only, but if we will put a number greater than zero then it can be greater than 2 but here it is not. So 2 is the smallest number.
