Mathematics

# Hello, myself Joyee. I am very much weak at Math and never get good at it. Though i have so many problems to ask. PLZ help me. Firstly, I need to know about this problem. If Marie has twice as much money as Tim, who has three times as much money as William, What is the ratio of the amount of money William has to the amount of money of Marie has ? A) 1:8, B) 1:6, C) 1:4, D) 1:2, E) 2:1

$\frac{William}{Marie}=\frac{x}{6x}=\frac{1}{6} \Rightarrow 1:6$
