If the tiger has consumed 112 pounds of food in 8 days that's \( \frac{112}{8} \) = 14 pounds of food per day. The tiger needs to consume 210 - 112 = 98 more pounds of food to reach 210 pounds total. At 14 pounds of food per day that's \( \frac{98}{14} \) = 7 more days.

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

\( \frac{2}{8} \) ÷ \( \frac{1}{5} \) = \( \frac{2}{8} \) x \( \frac{5}{1} \)

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

\( \frac{2}{8} \) x \( \frac{5}{1} \) = \( \frac{2 x 5}{8 x 1} \) = \( \frac{10}{8} \) = 1\(\frac{1}{4}\)

If 72% of the town's 42,000 voters cast ballots the number of votes cast is:

(\( \frac{72}{100} \)) x 42,000 = \( \frac{3,024,000}{100} \) = 30,240

The mayor got 79% of the votes cast which is:

(\( \frac{79}{100} \)) x 30,240 = \( \frac{2,388,960}{100} \) = 23,890 votes.

The greatest common factor (GCF) is the greatest factor that divides two integers.

A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
