Final answer:
Toronto FC has won approximately 59.5% of the games they have played.
Step-by-step explanation:
To find the percentage of games that Toronto FC has won, we need to subtract the number of games they have lost and the number of games they have drawn from the total number of games they have played. Toronto FC has played a total of 40 games and lost 12 of them, which leaves us with 40 - 12 = 28 games remaining. Out of these 28 games, 15% of them have been drawn, so we need to subtract this percentage as well. 15% of 28 is 0.15 * 28 = 4.2 games. Subtracting 4.2 from 28 gives us 28 - 4.2 = 23.8 games.
Therefore, Toronto FC has won approximately 23.8 games out of the 40 games they have played.
To find the percentage of games that they have won, we can divide the number of games they have won by the total number of games they have played and multiply by 100. Percentage of games won = (23.8 / 40) * 100 = 59.5%.
