Average speed in miles per hour is the number of miles traveled divided by the number of hours:

You have 12 out of the total of 400 raffle tickets sold so you have a (\( \frac{12}{400} \)) x 100 = \( \frac{12 \times 100}{400} \) = \( \frac{1200}{400} \) = 3% chance to win the raffle.

April scored 86% on the test meaning she earned 86% of the possible points on the test. There were 210 possible points on the test so she earned 210 x 0.86 = 180 points. Each question is worth 3 points so she got \( \frac{180}{3} \) = 60 questions right.

To divide fractions, invert the second fraction and then multiply:

\( \frac{3}{6} \) ÷ \( \frac{1}{8} \) = \( \frac{3}{6} \) x \( \frac{8}{1} \)

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

\( \frac{3}{6} \) x \( \frac{8}{1} \) = \( \frac{3 x 8}{6 x 1} \) = \( \frac{24}{6} \) = 4

If 35% of the town's 10,000 voters cast ballots the number of votes cast is:

(\( \frac{35}{100} \)) x 10,000 = \( \frac{350,000}{100} \) = 3,500

The mayor got 86% of the votes cast which is:

(\( \frac{86}{100} \)) x 3,500 = \( \frac{301,000}{100} \) = 3,010 votes.
