A bread recipe calls for 2 cups of flour. If you only have 1\(\frac{5}{8}\) cups, how much more flour is needed?
| 1\(\frac{1}{8}\) cups | |
| 1\(\frac{3}{4}\) cups | |
| 1\(\frac{7}{8}\) cups | |
| \(\frac{3}{8}\) cups |
The amount of flour you need is (2 - 1\(\frac{5}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{16}{8} \) - \( \frac{13}{8} \)) cups
\( \frac{3}{8} \) cups
\(\frac{3}{8}\) cups
What is the distance in miles of a trip that takes 9 hours at an average speed of 40 miles per hour?
| 560 miles | |
| 150 miles | |
| 360 miles | |
| 75 miles |
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 distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 40mph \times 9h \)
360 miles
Which of the following is an improper fraction?
\({a \over 5} \) |
|
\(1 {2 \over 5} \) |
|
\({2 \over 5} \) |
|
\({7 \over 5} \) |
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.
How many 9-passenger vans will it take to drive all 32 members of the football team to an away game?
| 6 vans | |
| 7 vans | |
| 5 vans | |
| 4 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{32}{9} \) = 3\(\frac{5}{9}\)
So, it will take 3 full vans and one partially full van to transport the entire team making a total of 4 vans.
