Major League Baseball is divided into the National League and the American League. The World Series championship is a “best-of-seven” series between the National League champion and the American League champion; the first team to win four games wins the series. Between 1903 and 2009 there have been 105 World Series and an American League team has won 62 of those championships. What percent of the 105 World Series were won by a National League team? Express your answer to the nearest whole percent.

That is a long way to ask you to convert 43/105 to a percent.

105 - 62 = 43 is, obviously, the number of World Series won by the National League, during that interval.

To find the percentage of World Series won by a National League team, we need to calculate the number of World Series won by a National League team and divide it by the total number of World Series (105). We can then multiply by 100 to get the percentage.

To find the number of World Series won by a National League team, we subtract the number of championships won by an American League team (62) from the total number of championships (105):

105 - 62 = 43

So, a National League team has won 43 World Series championships.

Now we can calculate the percentage:

(43 / 105) * 100 = 40.95

Rounded to the nearest whole percent, the National League has won approximately 41% of the 105 World Series championships.
