Question
If 3A = 4B = 6C, find A : B : C
✓
Answer
$
\begin{aligned}
& 3 A =4 B \\
& \Rightarrow \frac{ A }{ B }=\frac{4}{3}
\end{aligned}
$
or
$
\begin{aligned}
& A: B=4: 3 \\
& \text { and } 4 B=6 C \\
& \Rightarrow \frac{B}{C}=\frac{6}{4}=\frac{3}{2}
\end{aligned}
$
or
$
\begin{aligned}
& C=3: 2 \\
& \therefore A: B: C=4: 3: 2 .
