To determine what fraction of the kites in the sky are striped, follow these steps:
1. Identify the total number of kites. In this case, there are 11 kites in total.
2. Identify the number of striped kites. There are 6 striped kites.
3. To find the fraction of kites that are striped, use the ratio of the number of striped kites to the total number of kites.
[tex]\[ \text{Fraction of striped kites} = \frac{\text{Number of striped kites}}{\text{Total number of kites}} \][/tex]
Substitute the given numbers into the equation:
[tex]\[ \text{Fraction of striped kites} = \frac{6}{11} \][/tex]
Thus, the fraction of the kites that are striped is [tex]\( \frac{6}{11} \)[/tex].
Therefore, the correct answer is:
[tex]\[ \boxed{\frac{6}{11}} \][/tex]
