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

\( \frac{1}{9} \) ÷ \( \frac{1}{8} \) = \( \frac{1}{9} \) x \( \frac{8}{1} \)

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

\( \frac{1}{9} \) x \( \frac{8}{1} \) = \( \frac{1 x 8}{9 x 1} \) = \( \frac{8}{9} \) = \(\frac{8}{9}\)

If 42% of the town's 50,000 voters cast ballots the number of votes cast is:

(\( \frac{42}{100} \)) x 50,000 = \( \frac{2,100,000}{100} \) = 21,000

The mayor got 82% of the votes cast which is:

(\( \frac{82}{100} \)) x 21,000 = \( \frac{1,722,000}{100} \) = 17,220 votes.

To fill a 15 gallon tank exactly halfway you'll need 7\(\frac{1}{2}\) gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:

cans = \( \frac{7\frac{1}{2} \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 5

A factor is a positive integer that divides evenly into a given number. For example, the factors of 8 are 1, 2, 4, and 8.

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