Question 2 of 5

How many pints are in 56 ounces?

Correct Answer: B

Rationale: To convert ounces to pints, you need to know that there are 16 ounces in a pint. To find out how many pints are in 56 ounces, you divide 56 by 16 (56 ounces � 16 ounces/pint), which equals 3.5 pints. Therefore, there are 3.5 pints in 56 ounces.

Question 3 of 5

What is the result of adding 2/3 and 4/9?

Correct Answer: A

Rationale: To add 2/3 and 4/9, you need to find a common denominator. In this case, the common denominator is 9. Convert 2/3 to 6/9. Now, the addition becomes 6/9 + 4/9 = 10/9. Simplifying 10/9 gives you 1 (1/9). Therefore, the correct answer is 1 (1/9). When adding fractions, having a common denominator is essential for accurate calculation.

Question 4 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 5 of 5

In the ratio 0.6 : X :: 7 : 42, what is X?

Correct Answer: B

Rationale: To find the value of X in the given ratio, set up the proportion: (0.6/X) = (7/42). Simplifying this, we get (0.6/X) = (1/6). Cross multiplying gives 0.6 * 6 = X, which results in X = 3.6. Therefore, the correct answer is 3.6, representing the value of X in the given ratio.
