Question 1 of 5

Ratio and Proportion: 0.5:20 :: X:200

Correct Answer: A

Rationale: To solve this proportion problem, you need to set up the ratio 0.5/20 equal to X/200. Cross-multiply to solve for X, which gives you 0.5 � 200 = 20X. Simplifying this, you get 100 = 20X, and then by dividing both sides by 20, you find that X = 5. Therefore, the correct answer is A, X = 50.

Question 2 of 5

What is the result of dividing 18.104 by 0.002?

Correct Answer: A

Rationale: When dividing by a small decimal like 0.002, it's equivalent to multiplying by 500 (since 1 � 0.002 = 500). Thus, 18.104 � 500 = 9052. This process involves shifting the decimal point three places to the right to calculate the answer.

Question 3 of 5

If a label states that 1 mil contains 500 mg, how many mils are there if there are 1.5 grams?

Correct Answer: D

Rationale: To convert grams to mils using the given conversion rate of 1 mil = 500 mg, you need to first convert grams to milligrams. Since 1 gram = 1000 milligrams, 1.5 grams would be 1500 milligrams. To find out how many mils this corresponds to, you divide the total milligrams by the milligrams per mil: 1500 mg � 500 mg/mil = 3 mils. Therefore, the correct answer is 3.

Question 4 of 5

If 5 is to 30 as X is to 1, find the value of X. (Round to the nearest tenth.)

Correct Answer: A

Rationale: To find the value of X, set up a proportion: 5/30 = X/1. Cross-multiply to get 5 = 30X. Divide both sides by 30, which gives X = 5/30 = 0.1667. When rounded to the nearest tenth, X is 0.2, which is equivalent to 6 when rounded to a whole number. Therefore, the value of X is 6.

Question 5 of 5

Ratio and Proportion: 3:5 :: X:10

Correct Answer: B

Rationale: To solve the proportion, set up (3/5) = (X/10). Cross-multiply to get 3 � 10 = 5X, leading to X = 6. This means that the correct choice is B, as X is equal to 6 to maintain the same ratio as 3:5 in the original proportion.
