The total games played represent 100%
If you add the wins (W), loses (L) and ties (T), you'll get the total games played:
[tex]100=W+L+T[/tex]If the percentage of wins is W=50%
and the percentage of loses is L=42%
You can calculate the ties as:
[tex]\begin{gathered} 50+42+T=100 \\ 92+T=100 \\ T=100-92 \\ T=8 \end{gathered}[/tex]8% of their games were tied
