Answer 1

Answer:

b) 2020

Explanation:

In the number 0.2020 , we can take out 0 from the end the number will remain the same.

In the number 20.20 , we can take out 0 from the last and still the number will be the same

In the number , 02.020 also , we can take out 0 from the last and still the number remains the same

In the number 2020 (option B) If a 0 is removed than the value of the number will change so all the 0's are significant in this number.
