Question 1 of 5
A die is rolled. What is the probability of getting a 5?
Correct Answer: C
Rationale: The probability of rolling a specific number on a fair six-sided die is calculated by taking the total number of favorable outcomes (which is 1 in this case, as there is only one face with a 5) divided by the total possible outcomes (which is 6 for a standard die). Therefore, the probability of rolling a 5 is 1/6, which is approximately 16.6%. To convert the probability to a percentage, you multiply the fraction by 100, giving you 16.6%. Hence, the correct answer is C, 16.60%.
Question 2 of 5
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?
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.
Question 3 of 5
Multiply: 2/3 x 3/5 =
Correct Answer: C
Rationale: To multiply fractions, multiply the numerators and the denominators: (2 x 3) / (3 x 5) = 6/15. Simplifying gives 2/5. Thus, the correct answer is C) 2/5.
Question 4 of 5
What is the result of adding 5 1/3 + 3 1/2?
Correct Answer: C
Rationale: To add mixed numbers, convert them to improper fractions. 5 1/3 = 16/3 and 3 1/2 = 7/2. Find a common denominator, in this case, 6: 16/3 = 32/6 and 7/2 = 21/6. Add the fractions: 32/6 + 21/6 = 53/6, which simplifies to 8 5/6. Therefore, the sum of 5 1/3 + 3 1/2 is 8 5/6.
Question 5 of 5
Ratio and Proportion: 100:2 :: 60:X
Correct Answer: D
Rationale: To solve for X, set up the proportion: (100/2) = (60/X). Cross-multiply to get 100X = 120. Divide by 100 to isolate X, giving X = 1.2. Therefore, X = 1.6.
