If there were a total of 400 raffle tickets sold and you bought 32 tickets, what's the probability that you'll win the raffle?
| 4% | |
| 13% | |
| 16% | |
| 8% |
You have 32 out of the total of 400 raffle tickets sold so you have a (\( \frac{32}{400} \)) x 100 = \( \frac{32 \times 100}{400} \) = \( \frac{3200}{400} \) = 8% chance to win the raffle.
A bread recipe calls for 3\(\frac{3}{8}\) cups of flour. If you only have 1 cup, how much more flour is needed?
| 1\(\frac{1}{8}\) cups | |
| 2\(\frac{1}{8}\) cups | |
| \(\frac{3}{8}\) cups | |
| 2\(\frac{3}{8}\) cups |
The amount of flour you need is (3\(\frac{3}{8}\) - 1) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{27}{8} \) - \( \frac{8}{8} \)) cups
\( \frac{19}{8} \) cups
2\(\frac{3}{8}\) cups
The __________ is the greatest factor that divides two integers.

Which of the following is a mixed number?
\({5 \over 7} \) |
|
\({7 \over 5} \) |
|
\({a \over 5} \) |

\(1 {2 \over 5} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
