To find the ratio \( A : B : C \), we start by understanding the given condition \(\frac{A}{4} = \frac{B}{5} = \frac{C}{6}\). This equation implies that all three fractions are equal to a common variable, say \( k \). Therefore, we can write:
Substituting the values of \( A \), \( B \), and \( C \) in terms of \( k \), the ratio \( A : B : C \) becomes:
\(4k : 5k : 6k\)
We can simplify this ratio by dividing each term by \( k \), resulting in:
\(4 : 5 : 6\)
Thus, the correct answer is:
This ratio satisfies the condition given in the problem that \(\frac{A}{4} = \frac{B}{5} = \frac{C}{6}\) because each term in the ratio is consistent with the proportional representations of \( A \), \( B \), and \( C \). Therefore, the correct answer is 4 : 5 : 6.
