How many 1 gallon cans worth of fuel would you need to pour into an empty 8 gallon tank to fill it exactly halfway?
| 3 | |
| 4 | |
| 6 | |
| 9 |
To fill a 8 gallon tank exactly halfway you'll need 4 gallons of fuel. Each fuel can holds 1 gallons so:
cans = \( \frac{4 \text{ gallons}}{1 \text{ gallons}} \) = 4
What is \( \frac{2}{9} \) x \( \frac{3}{6} \)?
| \(\frac{1}{9}\) | |
| \(\frac{2}{5}\) | |
| 1 | |
| \(\frac{1}{28}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{2}{9} \) x \( \frac{3}{6} \) = \( \frac{2 x 3}{9 x 6} \) = \( \frac{6}{54} \) = \(\frac{1}{9}\)
Monica scored 76% on her final exam. If each question was worth 4 points and there were 400 possible points on the exam, how many questions did Monica answer correctly?
| 72 | |
| 76 | |
| 73 | |
| 86 |
Monica scored 76% on the test meaning she earned 76% of the possible points on the test. There were 400 possible points on the test so she earned 400 x 0.76 = 304 points. Each question is worth 4 points so she got \( \frac{304}{4} \) = 76 questions right.
How many 10-passenger vans will it take to drive all 62 members of the football team to an away game?
| 7 vans | |
| 4 vans | |
| 6 vans | |
| 10 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{62}{10} \) = 6\(\frac{1}{5}\)
So, it will take 6 full vans and one partially full van to transport the entire team making a total of 7 vans.
If all of a roofing company's 8 workers are required to staff 2 roofing crews, how many workers need to be added during the busy season in order to send 6 complete crews out on jobs?
| 15 | |
| 16 | |
| 11 | |
| 18 |
In order to find how many additional workers are needed to staff the extra crews you first need to calculate how many workers are on a crew. There are 8 workers at the company now and that's enough to staff 2 crews so there are \( \frac{8}{2} \) = 4 workers on a crew. 6 crews are needed for the busy season which, at 4 workers per crew, means that the roofing company will need 6 x 4 = 24 total workers to staff the crews during the busy season. The company already employs 8 workers so they need to add 24 - 8 = 16 new staff for the busy season.
