How many 8-passenger vans will it take to drive all 54 members of the football team to an away game?
| 14 vans | |
| 5 vans | |
| 3 vans | |
| 7 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{54}{8} \) = 6\(\frac{3}{4}\)
So, it will take 6 full vans and one partially full van to transport the entire team making a total of 7 vans.
A bread recipe calls for 2\(\frac{1}{4}\) cups of flour. If you only have \(\frac{1}{4}\) cup, how much more flour is needed?
| 2 cups | |
| 1\(\frac{7}{8}\) cups | |
| 2\(\frac{3}{4}\) cups | |
| 2\(\frac{3}{8}\) cups |
The amount of flour you need is (2\(\frac{1}{4}\) - \(\frac{1}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{18}{8} \) - \( \frac{2}{8} \)) cups
\( \frac{16}{8} \) cups
2 cups

A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 40% off." If Frank buys two shirts, each with a regular price of $34, how much money will he save?
| $13.60 | |
| $3.40 | |
| $17.00 | |
| $1.70 |
By buying two shirts, Frank will save $34 x \( \frac{40}{100} \) = \( \frac{$34 x 40}{100} \) = \( \frac{$1360}{100} \) = $13.60 on the second shirt.
