The number 0.010989011 rounded to four decimal places is 0.0110 because the fifth digit after the decimal is a 9, which requires rounding up.

Step-by-step explanation:

To simplify the number 0.010989011 to 4 decimal places, we need to look at the fifth decimal place to decide whether to round the fourth place up or leave it as is. If the fifth decimal digit is 5 or greater, we round up. In this case, the fifth decimal is a 9, which is greater than 5, so we round up the fourth decimal place from 8 to 9.
