Step-by-step explanation:

A : B = 20 : 24 ----------------- (1)

B : C = (4 : 7) * 6

B : C = 24 : 42 ------------------- (2)

A : B : C = 20 : 24 : 42

A : B : C = 10 : 12 : 21.

\frac{a}{b}=\frac{4}{7}×\frac{5}{5}=\frac{20}{35}

\frac{b}{c}=\frac{5}{7} ×\frac{7}{7}=\frac{35}{49}

   a  :  b  :  c

<strong> </strong><strong>20 : 35 : 49</strong>
