Find the Pct for 10 games won and 8 games lost. Round to the nearest thousandth.

It's always easy to do these as a fraction. We want won/total games played.

Games = 8 + 10 or 18 games played.

pct = 10/18

pct = 0.5555555556

Round to 3 decimal places.

pct = 0.556

Multiply pct by 100.

So, 0.556 • 100 = 55.6.

The pct sought is 55.6%.
