A. 1/34
B. 1/16
C. 8/17
D. 8/9

It would be 1/34 or 1/16.

Step-by-step explanation:

Add up how many kids there are in total and then see how many girls there are and write it like this: 18/34. Since it says a girl then you would do it as 1/34 or 1/16 it depends on how you look at it and or how you understand what the question is talking about.

it would be 6xy and -16xy.
