What is \( \frac{3}{6} \) ÷ \( \frac{3}{9} \)?
| 4\(\frac{1}{2}\) | |
| \(\frac{2}{21}\) | |
| \(\frac{1}{6}\) | |
| 1\(\frac{1}{2}\) |
To divide fractions, invert the second fraction and then multiply:
\( \frac{3}{6} \) ÷ \( \frac{3}{9} \) = \( \frac{3}{6} \) x \( \frac{9}{3} \)
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{6} \) x \( \frac{9}{3} \) = \( \frac{3 x 9}{6 x 3} \) = \( \frac{27}{18} \) = 1\(\frac{1}{2}\)
On average, the center for a basketball team hits 40% of his shots while a guard on the same team hits 55% of his shots. If the guard takes 25 shots during a game, how many shots will the center have to take to score as many points as the guard assuming each shot is worth the same number of points?
| 59 | |
| 29 | |
| 24 | |
| 33 |
guard shots made = shots taken x \( \frac{\text{% made}}{100} \) = 25 x \( \frac{55}{100} \) = \( \frac{55 x 25}{100} \) = \( \frac{1375}{100} \) = 13 shots
The center makes 40% of his shots so he'll have to take:
shots made = shots taken x \( \frac{\text{% made}}{100} \)
shots taken = \( \frac{\text{shots taken}}{\frac{\text{% made}}{100}} \)
to make as many shots as the guard. Plugging in values for the center gives us:
center shots taken = \( \frac{13}{\frac{40}{100}} \) = 13 x \( \frac{100}{40} \) = \( \frac{13 x 100}{40} \) = \( \frac{1300}{40} \) = 33 shots
to make the same number of shots as the guard and thus score the same number of points.
What is the next number in this sequence: 1, 2, 3, 4, 5, __________ ?
| 6 | |
| 0 | |
| 5 | |
| 1 |
The equation for this sequence is:
an = an-1 + 1
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 1
a6 = 5 + 1
a6 = 6

A factor is a positive integer that divides evenly into a given number. For example, the factors of 8 are 1, 2, 4, and 8.
If the ratio of home fans to visiting fans in a crowd is 4:1 and all 41,000 seats in a stadium are filled, how many home fans are in attendance?
| 26,667 | |
| 32,800 | |
| 36,667 | |
| 33,333 |
A ratio of 4:1 means that there are 4 home fans for every one visiting fan. So, of every 5 fans, 4 are home fans and \( \frac{4}{5} \) of every fan in the stadium is a home fan:
41,000 fans x \( \frac{4}{5} \) = \( \frac{164000}{5} \) = 32,800 fans.
