Well, there are 8 boys and the brother is one of them so 1 is 12.5% of 8 and out of 10 girls, there 1 is the sister and 1 out of 10 is 10%. Now we multiply the percentages to get the answer 1/80

Answer:
Take the y not the 7, or 9 and divide that by the qq. Before we divide it by the qq of its c we have to find the qq. I assume you already know the qq but if you don't heres how we find it. Take the 65 in the 9 by subtracting the 199 and then multiplying that by the same number we used in the begging. Y, which is and isn't a number at the same time. It is a letter, yes. But in this case it stands for a number. Assuming you already know the number, 15 you add that to 65, which would give you 80. Easy math, right? Haha. So to get your answer just multiply what you asked me in the first place. Hope this helps u!
