What is \( \frac{3}{6} \) x \( \frac{4}{9} \)?
| \(\frac{2}{9}\) | |
| \(\frac{8}{49}\) | |
| 2 | |
| \(\frac{1}{12}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{6} \) x \( \frac{4}{9} \) = \( \frac{3 x 4}{6 x 9} \) = \( \frac{12}{54} \) = \(\frac{2}{9}\)

If a mayor is elected with 82% of the votes cast and 61% of a town's 12,000 voters cast a vote, how many votes did the mayor receive?
| 4,538 | |
| 3,806 | |
| 6,002 | |
| 3,953 |
If 61% of the town's 12,000 voters cast ballots the number of votes cast is:
(\( \frac{61}{100} \)) x 12,000 = \( \frac{732,000}{100} \) = 7,320
The mayor got 82% of the votes cast which is:
(\( \frac{82}{100} \)) x 7,320 = \( \frac{600,240}{100} \) = 6,002 votes.
A bread recipe calls for 2\(\frac{7}{8}\) cups of flour. If you only have \(\frac{1}{4}\) cup, how much more flour is needed?
| 1\(\frac{5}{8}\) cups | |
| 2\(\frac{5}{8}\) cups | |
| 1\(\frac{3}{8}\) cups | |
| 3\(\frac{1}{8}\) cups |
The amount of flour you need is (2\(\frac{7}{8}\) - \(\frac{1}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{23}{8} \) - \( \frac{2}{8} \)) cups
\( \frac{21}{8} \) cups
2\(\frac{5}{8}\) cups
Monty loaned Roger $1,300 at an annual interest rate of 3%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $39 | |
| $27 | |
| $2 | |
| $65 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $1,300
i = 0.03 x $1,300
i = $39
