What is \( \frac{4}{9} \) x \( \frac{2}{6} \)?
| \(\frac{4}{27}\) | |
| \(\frac{1}{12}\) | |
| \(\frac{1}{9}\) | |
| \(\frac{1}{28}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{9} \) x \( \frac{2}{6} \) = \( \frac{4 x 2}{9 x 6} \) = \( \frac{8}{54} \) = \(\frac{4}{27}\)
Simplify \( \sqrt{50} \)
| 5\( \sqrt{2} \) | |
| 3\( \sqrt{2} \) | |
| 7\( \sqrt{4} \) | |
| 2\( \sqrt{2} \) |
To simplify a radical, factor out the perfect squares:
\( \sqrt{50} \)
\( \sqrt{25 \times 2} \)
\( \sqrt{5^2 \times 2} \)
5\( \sqrt{2} \)
If the ratio of home fans to visiting fans in a crowd is 2:1 and all 41,000 seats in a stadium are filled, how many home fans are in attendance?
| 24,667 | |
| 24,750 | |
| 27,333 | |
| 25,833 |
A ratio of 2:1 means that there are 2 home fans for every one visiting fan. So, of every 3 fans, 2 are home fans and \( \frac{2}{3} \) of every fan in the stadium is a home fan:
41,000 fans x \( \frac{2}{3} \) = \( \frac{82000}{3} \) = 27,333 fans.

Latoya scored 77% on her final exam. If each question was worth 4 points and there were 280 possible points on the exam, how many questions did Latoya answer correctly?
| 41 | |
| 61 | |
| 54 | |
| 47 |
Latoya scored 77% on the test meaning she earned 77% of the possible points on the test. There were 280 possible points on the test so she earned 280 x 0.77 = 216 points. Each question is worth 4 points so she got \( \frac{216}{4} \) = 54 questions right.
