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?
| 2\(\frac{3}{8}\) cups | |
| 2\(\frac{1}{2}\) cups | |
| 2\(\frac{5}{8}\) cups | |
| 1\(\frac{7}{8}\) 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
If there were a total of 300 raffle tickets sold and you bought 24 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 8% | |
| 3% | |
| 4% |
You have 24 out of the total of 300 raffle tickets sold so you have a (\( \frac{24}{300} \)) x 100 = \( \frac{24 \times 100}{300} \) = \( \frac{2400}{300} \) = 8% chance to win the raffle.
Christine scored 93% on her final exam. If each question was worth 3 points and there were 90 possible points on the exam, how many questions did Christine answer correctly?
| 26 | |
| 43 | |
| 25 | |
| 28 |
Christine scored 93% on the test meaning she earned 93% of the possible points on the test. There were 90 possible points on the test so she earned 90 x 0.93 = 84 points. Each question is worth 3 points so she got \( \frac{84}{3} \) = 28 questions right.

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.
