A bread recipe calls for 3\(\frac{3}{8}\) cups of flour. If you only have 1\(\frac{3}{8}\) cups, how much more flour is needed?
| 1\(\frac{1}{4}\) cups | |
| 1\(\frac{3}{8}\) cups | |
| 2 cups | |
| \(\frac{7}{8}\) cups |
The amount of flour you need is (3\(\frac{3}{8}\) - 1\(\frac{3}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{27}{8} \) - \( \frac{11}{8} \)) cups
\( \frac{16}{8} \) cups
2 cups
April scored 89% on her final exam. If each question was worth 4 points and there were 400 possible points on the exam, how many questions did April answer correctly?
| 75 | |
| 77 | |
| 89 | |
| 95 |
April scored 89% on the test meaning she earned 89% of the possible points on the test. There were 400 possible points on the test so she earned 400 x 0.89 = 356 points. Each question is worth 4 points so she got \( \frac{356}{4} \) = 89 questions right.
How many 2 gallon cans worth of fuel would you need to pour into an empty 12 gallon tank to fill it exactly halfway?
| 7 | |
| 3 | |
| 3 | |
| 6 |
To fill a 12 gallon tank exactly halfway you'll need 6 gallons of fuel. Each fuel can holds 2 gallons so:
cans = \( \frac{6 \text{ gallons}}{2 \text{ gallons}} \) = 3

How many hours does it take a car to travel 270 miles at an average speed of 45 miles per hour?
| 8 hours | |
| 9 hours | |
| 6 hours | |
| 4 hours |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for time:
time = \( \frac{\text{distance}}{\text{speed}} \)
time = \( \frac{270mi}{45mph} \)
6 hours
