If 30% of the town's 25,000 voters cast ballots the number of votes cast is:

(\( \frac{30}{100} \)) x 25,000 = \( \frac{750,000}{100} \) = 7,500

The mayor got 60% of the votes cast which is:

(\( \frac{60}{100} \)) x 7,500 = \( \frac{450,000}{100} \) = 4,500 votes.

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

\( \frac{4}{9} \) ÷ \( \frac{4}{6} \) = \( \frac{4}{9} \) x \( \frac{6}{4} \)

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

\( \frac{4}{9} \) x \( \frac{6}{4} \) = \( \frac{4 x 6}{9 x 4} \) = \( \frac{24}{36} \) = \(\frac{2}{3}\)

Betty scored 73% on the test meaning she earned 73% of the possible points on the test. There were 60 possible points on the test so she earned 60 x 0.73 = 44 points. Each question is worth 2 points so she got \( \frac{44}{2} \) = 22 questions right.

The amount of flour you need is (2\(\frac{5}{8}\) - 1\(\frac{1}{2}\)) cups. Rewrite the quantities so they share a common denominator and subtract:

(\( \frac{21}{8} \) - \( \frac{12}{8} \)) cups
\( \frac{9}{8} \) cups
1\(\frac{1}{8}\) cups

An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.
