To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 400 meters to kilometers, divide the distance by 1000 to get 0.4km then add the remaining distances:

total distance = swim + bike + run
total distance = 0.4km + 50.1km + 12.9km
total distance = 63.4km

If 81% of the town's 22,000 voters cast ballots the number of votes cast is:

(\( \frac{81}{100} \)) x 22,000 = \( \frac{1,782,000}{100} \) = 17,820

The mayor got 74% of the votes cast which is:

(\( \frac{74}{100} \)) x 17,820 = \( \frac{1,318,680}{100} \) = 13,187 votes.

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{1}{9} \) x \( \frac{2}{5} \) = \( \frac{1 x 2}{9 x 5} \) = \( \frac{2}{45} \) = \(\frac{2}{45}\)

You have 18 out of the total of 450 raffle tickets sold so you have a (\( \frac{18}{450} \)) x 100 = \( \frac{18 \times 100}{450} \) = \( \frac{1800}{450} \) = 4% chance to win the raffle.
