How many 1\(\frac{1}{2}\) gallon cans worth of fuel would you need to pour into an empty 6 gallon tank to fill it exactly halfway?
| 2 | |
| 2 | |
| 4 | |
| 7 |
To fill a 6 gallon tank exactly halfway you'll need 3 gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:
cans = \( \frac{3 \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 2

Damon loaned Jennifer $400 at an annual interest rate of 1%. If no payments are made, what is the total amount owed at the end of the first year?
| $408 | |
| $416 | |
| $404 | |
| $428 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $400
i = 0.01 x $400
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $400 + $4If a mayor is elected with 55% of the votes cast and 30% of a town's 41,000 voters cast a vote, how many votes did the mayor receive?
| 9,963 | |
| 9,717 | |
| 6,765 | |
| 7,749 |
If 30% of the town's 41,000 voters cast ballots the number of votes cast is:
(\( \frac{30}{100} \)) x 41,000 = \( \frac{1,230,000}{100} \) = 12,300
The mayor got 55% of the votes cast which is:
(\( \frac{55}{100} \)) x 12,300 = \( \frac{676,500}{100} \) = 6,765 votes.
Which of the following is a mixed number?
\({a \over 5} \) |
|
\({7 \over 5} \) |
|
\({5 \over 7} \) |
|
\(1 {2 \over 5} \) |
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.
