- A.
2/4
- B.
5/9
- C.
5/8
- D.
9/5
Correct Answer
B. 5/9Explanation

A recipe calls for 2 cups of flour for every 3 cups of sugar. If you use 8 cups of flour, how many cups of sugar will you need?
- A.
10 cups
- B.
12 cups
- C.
14 cups
- D.
16 cups
Correct Answer
B. 12 cupsExplanation
The recipe provides a ratio of flour to sugar, which is 2:3. To maintain the same proportion when using 8 cups of flour, we need to find an equivalent ratio. We can do this by multiplying both sides of the ratio 2:3 by 4. This gives us 8:12. Therefore, to use 8 cups of flour while keeping the proportions of the recipe the same, you would need 12 cups of sugar.Rate this question:

If 10 workers can complete a job in 6 days, how many days will it take 15 workers to complete the same job?
- A.
3 days
- B.
4 days
- C.
5 days
- D.
6 days
Correct Answer
B. 4 daysExplanation
This type of problem involves an inverse proportion. This means that as the number of workers increases, the time taken to complete the job decreases. We can set up a proportion to solve this: 10 workers / 15 workers = x days / 6 days. To find the value of x (the number of days for 15 workers), we cross-multiply and solve the equation. This gives us x = (10 x 6) / 15 = 4 days.Rate this question:

A car travels 240 miles in 4 hours. At this rate, how far will it travel in 7 hours?
- A.
350 miles
- B.
380 miles
- C.
420 miles
- D.
450 miles
Explanation
First, we find the car's speed: 240 miles / 4 hours = 60 miles per hour. Then, to find the distance traveled in 7 hours, we multiply the speed by the time: 60 miles/hour x 7 hours = 420 miles.Rate this question:
