Step-by-step explanation:
To find the percent of players on the chess team who are seventh graders, divide the number of seventh graders by the total number of players on the team and multiply by 100. Round your answer to the nearest tenth.
Let's say there are 10 players on the chess team and 3 of them are seventh graders. The percent of seventh graders on the team would be (3/10) * 100 = 30%. Rounded to the nearest tenth, the answer is 33.3% (option b).
