Make the common term (Team B) the same in both ratios, then compare Team C to Team A.<br><br>
&bull; Team A : Team B = \(10 : 3 = 20 : 6\)<br>
&bull; Team C : Team B = \(5 : 6\)<br>
&bull; So Team A : Team B : Team C = \(20 : 6 : 5\)<br>
&bull; \(\frac{\text{Team C}}{\text{Team A}} = \frac{5}{20} = \frac{1}{4}\)<br><br>
Final Answer: x = 1, y = 4
