To write $\frac{11}{18}$ as a decimal, we'll perform the division $11 \div 18$.

Let's calculate:

1. Divide 11 by 18: $11 \div 18 = 0.611111\ldots$ The result is $0.611111\ldots$, where the digit "1" repeats indefinitely.

2. Expressing the decimal: Since the digit "1" repeats, we can write the decimal as: $0.6\overline{1}$ The bar over the "1" indicates that it repeats.

Therefore, $\frac{11}{18}$ as a decimal is $0.6\overline{1}$.
