Final answer:
Ivanna received votes from 40 percent of the chess club members, calculated by dividing 22 votes by 55 members and multiplying by 100%.
Step-by-step explanation:
To find the percentage of club members who voted for Ivanna in the chess club's presidential election, we use the formula for calculating percentage:
Percentage = (Number of votes for Ivanna / Total number of club members) × 100%
We know that Ivanna received 22 votes, and the total number of club members is 55. Plugging these values into our formula gives us:
Percentage = (22 / 55) × 100% = 0.4 × 100% = 40%
Therefore, Ivanna received votes from 40 percent of the club members.
