We can convert this to a decimal by dividing the two numbers. Use a calculator:
And we can convert this to a percent by moving the decimal too places to the right and by adding a percent sign:
So, about 83.33% of members on Team A was present.

Change this to a percent:
So, Team A had a participation rate of 83.33% while Team B had a participation rate of 86.67%.
So, the team that had the lesser percent of the team present at the tournament is Team A.
And we're done!
