A bread recipe calls for 3\(\frac{1}{2}\) cups of flour. If you only have \(\frac{3}{4}\) cup, how much more flour is needed?
| 1\(\frac{1}{2}\) cups | |
| 2\(\frac{3}{8}\) cups | |
| 2\(\frac{3}{4}\) cups | |
| 1\(\frac{3}{8}\) cups |
The amount of flour you need is (3\(\frac{1}{2}\) - \(\frac{3}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{28}{8} \) - \( \frac{6}{8} \)) cups
\( \frac{22}{8} \) cups
2\(\frac{3}{4}\) cups
9 members of a bridal party need transported to a wedding reception but there are only 2 2-passenger taxis available to take them. How many will need to find other transportation?
| 2 | |
| 4 | |

There are 2 2-passenger taxis available so that's 2 x 2 = 4 total seats. There are 9 people needing transportation leaving 9 - 4 = 5 who will have to find other transportation.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 30% off." If Bob buys two shirts, each with a regular price of $10, how much money will he save?
| $5.00 | |
| 67 | |
| $4.00 | |
| $3.00 |
By buying two shirts, Bob will save $10 x \( \frac{30}{100} \) = \( \frac{$10 x 30}{100} \) = \( \frac{$300}{100} \) = $3.00 on the second shirt.

What is \( \frac{3}{9} \) x \( \frac{3}{7} \)?
| \(\frac{1}{7}\) | |
| \(\frac{9}{35}\) | |
| 1 | |
| \(\frac{6}{35}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{9} \) x \( \frac{3}{7} \) = \( \frac{3 x 3}{9 x 7} \) = \( \frac{9}{63} \) = \(\frac{1}{7}\)
