Given :- Fill in the blank: The decimal expansion of 2/11 is ________.*
1️⃣ Terminating
2️⃣ Non terminating
3️⃣ Non terminating and repeating
4️⃣ Non terminating and non repeating
Answer :- 3️⃣ Non terminating and repeating .
Explanation :-
- we have to check prime factors of denominators of given fraction .
- if Prime factor are 2, or 5 , or 2 and 5 both . Than the given fraction is a terminating decimal expansion .
- if prime factors are other than 2 or 5 , than the given fraction is a non - terminating decimal expansion .
so,
→ 2/11 = denominator = 11
→ prime factors of 11 = 1 * 11 ≠ 2 or 5 .
therefore, 2/11 is Non terminating and repeating decimal .
[Note :- Non terminating and non repeating decimal are that continues endlessly, with no group of digits repeating .]
