If the tiger has consumed 104 pounds of food in 8 days that's \( \frac{104}{8} \) = 13 pounds of food per day. The tiger needs to consume 143 - 104 = 39 more pounds of food to reach 143 pounds total. At 13 pounds of food per day that's \( \frac{39}{13} \) = 3 more days.

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

\( \frac{1}{9} \) ÷ \( \frac{4}{8} \) = \( \frac{1}{9} \) x \( \frac{8}{4} \)

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

\( \frac{1}{9} \) x \( \frac{8}{4} \) = \( \frac{1 x 8}{9 x 4} \) = \( \frac{8}{36} \) = \(\frac{2}{9}\)

A number with an exponent (b^e) consists of a base (b) raised to a power (e). The exponent indicates the number of times that the base is multiplied by itself. A base with an exponent of 1 equals the base (b¹ = b) and a base with an exponent of 0 equals 1 ( (b⁰ = 1).

To fill a 25 gallon tank exactly halfway you'll need 12\(\frac{1}{2}\) gallons of fuel. Each fuel can holds 2\(\frac{1}{2}\) gallons so:

cans = \( \frac{12\frac{1}{2} \text{ gallons}}{2\frac{1}{2} \text{ gallons}} \) = 5

If 64% of the town's 31,000 voters cast ballots the number of votes cast is:

(\( \frac{64}{100} \)) x 31,000 = \( \frac{1,984,000}{100} \) = 19,840

The mayor got 75% of the votes cast which is:

(\( \frac{75}{100} \)) x 19,840 = \( \frac{1,488,000}{100} \) = 14,880 votes.
