15 members of a bridal party need transported to a wedding reception but there are only 4 3-passenger taxis available to take them. How many will need to find other transportation?
| 4 | |
| 8 | |
| 9 | |
| 3 |
There are 4 3-passenger taxis available so that's 4 x 3 = 12 total seats. There are 15 people needing transportation leaving 15 - 12 = 3 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 35% off." If Roger buys two shirts, each with a regular price of $46, how much money will he save?
| $16.10 | |
| $18.40 | |
| $20.70 | |
| $4.60 |
By buying two shirts, Roger will save $46 x \( \frac{35}{100} \) = \( \frac{$46 x 35}{100} \) = \( \frac{$1610}{100} \) = $16.10 on the second shirt.
Latoya scored 81% on her final exam. If each question was worth 3 points and there were 210 possible points on the exam, how many questions did Latoya answer correctly?
| 43 | |
| 57 | |
| 50 | |
| 62 |
Latoya scored 81% on the test meaning she earned 81% of the possible points on the test. There were 210 possible points on the test so she earned 210 x 0.81 = 171 points. Each question is worth 3 points so she got \( \frac{171}{3} \) = 57 questions right.
Which of the following is a mixed number?
\({a \over 5} \) |
|
\(1 {2 \over 5} \) |
|
\({5 \over 7} \) |
|
\({7 \over 5} \) |
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.
\({b + c \over a} = {b \over a} + {c \over a}\) defines which of the following?

distributive property for division |
The distributive property for division helps in solving expressions like \({b + c \over a}\). It specifies that the result of dividing a fraction with multiple terms in the numerator and one term in the denominator can be obtained by dividing each term individually and then totaling the results: \({b + c \over a} = {b \over a} + {c \over a}\). For example, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).
