Answer:
10!!
Step-by-step explanation:
10 x 3 = 30
10 + 10 + 10 = 30
The answer is D. because if there is 32 total, and 18 of them are girls, that means that there are 14 boys . with the question asking for girl/boy ratio it would have to be 18/14 in that order . if you divide 18 and 14 by two, they simple down to 9/7 . making the answer D.
