Answer:

12

Step-by-step explanation:

11.9781

After tenth digit it is 7>=5. So 1 should be added to 11.9

11.9 + 1 = 12.0 = 12

12 because when you’re rounding you if the number that needs to be rounded is 5 or more it becomes the next big number and if it’s 4 or less than it stays the same.

examples:
4.(2)54 —> 4.3
6.(3)27 —> 6.3
3.(3)81 —> 3.4
1.(2)11 —> 1.2
