Jawaban:
12/35
Penjelasan dengan langkah-langkah:
let the total money = x
farhan's share = 1/5 x -> remaining money = x-1/5 x = 4/5 x
khairul's share = 1/3(4/5 x) =4/15 x -> remaining money = 4/5 x-4/15 x = 8/15 x
huixian's share = 1/4(8/15 x) = 2/15 x-> remaining money = 8/15 x-2/15 x = 6/15 x
shirley's share = 1/7(6/15 x) = 6/105 x-> remaining money = 6/15 x-6/105 x = 12/35 x
so jun wei's share = 12/35 x
