Half of the students live on Hong Kong Island and 432 students live in Kowloon . The rest of the students live in the New Territories . Among the students who live in the New Territories , 4/9 of them live in Shatin and the rest of them live in Tsuen Wan. (a) What fraction of the students live in Tsuen Wan ? (b) If 1/2 of the students who live in Tsuen Wan now move to Hong Kong Island , then what fraction of the students are living on Hong Kong Island ? Thanks

最佳解答:

Ans : (1156-(1156/2+432))x5/9 =82 students =82/1156 students live in Tsuen Wan (b).=82/2 =41students left to Hong Kong Island (41+1156/2)/1156 = students are living on Hong Kong Island =619/1156 students

其他解答:

What fraction of the students live in Tsuen Wan ? (1156÷2)-432 =578-432 =146 146x4÷9 ≈65 146-65 ≈81 ------------------------------------------------------------------------------- If 1/2 of the students who live in Tsuen Wan now move to Hong Kong Island , then what fraction of the students are living on Hong Kong Island ? (81÷2)+578 =40.5+578 =618.5 =618.5/1156 I hope this answer will make you satisfied=]|||||no.2 is right , thanks :D|||||no, of students living on HK Island = 1156 / 2 = 578 no. of students living in Kowloon = 432 no. of students living in N.T. = 578 - 432 = 146 no. of students living in Sha Tin = 146 X (4 / 9) = 64 . 88888..... (please use calculator if you need the ans in the form of fraction) no. of students living in Tsuen Wan = 146 - 64.8888.... = 81.11111...... I think you can finish the rest on your own now. If you can't you can ask me.
