Question 347842
Since a:b=3:1, we know that {{{a/b=3/1}}}. Cross multiply to get {{{a=3b}}}. Then solve for 'b' to get {{{b=a/3}}}



In addition, we know that b:c=2:3 which tells us that {{{b/c=2/3}}}. We can then plug in {{{b=a/3}}} to get {{{(a/3)/c=2/3}}}. From here, simplify the equation and get it into the form {{{a/c=k/m}}} where 'k' and 'm' are some expressions. I'll let you take it from here.
