A production statistic shows that it takes 2 chickens to produce 6 eggs in 24 hours. How many chickens are needed to produce 24 eggs in 24 hours?

  • A. 3 chickens
  • B. 8 chickens
  • C. 12 chickens
  • D. 4 chickens
Correct Answer: B

Rationale: If 2 chickens produce 6 eggs in 24 hours, it means each chicken produces 3 eggs in 24 hours. To produce 24 eggs, you would need to calculate 24 eggs · 3 eggs per chicken = 8 chickens. Therefore, 8 chickens are needed to produce 24 eggs in 24 hours. This calculation is based on the proportionality of the number of chickens to the number of eggs produced, ensuring the correct quantity of chickens is determined for the desired egg output.

Which fraction represents the largest value?

  • A. 3/7
  • B. 3/6
  • C. 3/9
  • D. 3/8
Correct Answer: B

Rationale: To determine the largest fraction when the numerators are the same, compare the denominators. A smaller denominator indicates a larger fraction as it represents more significant parts of a whole. In this case, the fractions all have a common numerator of 3. Comparing the denominators, 6 is the smallest, making 3/6 the largest fraction. Therefore, 3/6 represents the largest value among the options. Remember, when fractions have the same numerator, the fraction with the smaller denominator is larger as it represents a larger portion of the whole.

To ride a certain amusement park attraction, a person must be 48 inches tall. How many feet tall must a person be to meet this requirement? (Enter a numeric value only.)

  • A. 4
  • B. 5
  • C. 6
  • D. 3
Correct Answer: A

Rationale: To convert inches to feet, you need to divide by 12 because there are 12 inches in a foot. Therefore, 48 inches · 12 = 4 feet. Hence, the correct answer is A) 4 feet.

What is 3 percent of 60?

  • A. 0.18
  • B. 1.8
  • C. 18
  • D. 0.018
Correct Answer: B

Rationale: To find 3% of 60, you multiply 60 by 3% (or 0.03).
So, 60 x 0.03 = 1.8.
Therefore, the correct answer is B: 1.8.
Choice A (0.18) is incorrect as it represents 0.3% of 60. Choice C (18) is incorrect as it represents 30% of 60. Choice D (0.018) is incorrect as it represents 0.03% of 60.

Ratio and Proportion: 200:2::20:X (Enter numeric value only.)

  • A. 2
  • B. 0.2
  • C. 4
  • D. 10
Correct Answer: B

Rationale: Correct Answer: B (0.2)

Rationale:
To solve this proportion problem, we can set up the equation:
200/2 = 20/X
Simplify the left side:
100 = 20/X
Cross multiply to solve for X:
100X = 20
Divide by 100 to isolate X:
X = 20/100
X = 0.2

Summary:
- Choice A (2) is incorrect as it does not match the calculated value of X.
- Choice C (4) is incorrect as it is not the correct answer derived from the proportion.
- Choice D (10) is incorrect as it does not align with the calculated value of X.

Express 0.608 as a percent.

  • A. 6.08%
  • B. 0.61%
  • C. 608%
  • D. 60.80%
Correct Answer: D

Rationale: To convert a decimal to a percent, multiply by 100. Therefore, 0.608 — 100 = 60.8%. Thus, the correct answer is D) 60.80%.
