Correct Answer: C

Rationale: The correct answer is C: 0.09%. To convert 0.0009 to a percentage, you move the decimal point two places to the right, resulting in 0.09%. Option A (0.009%) is incorrect as it would be the equivalent of 0.00009. Option B (0.9%) is incorrect as it represents 0.009.

Question 2 of 5

How many grams of carbohydrates are in a product if it contains 4 servings, and each serving has 8 grams of carbohydrates?

Correct Answer: A

Rationale: To calculate the total grams of carbohydrates in the product, you multiply the number of servings by the grams of carbohydrates per serving. In this case, 4 servings x 8 grams/serving = 32 grams of carbohydrates. Therefore, the correct answer is A. Explanation for other choices: B: 4 servings x 8 grams/serving does not equal 28 grams. C: 4 servings x 8 grams/serving does not equal 24 grams. D: 4 servings x 8 grams/serving does not equal 20 grams.

Question 3 of 5

Given 15:x=3:8, find x.

Correct Answer: A

Rationale: To find x, we need to set up a proportion: 15/x = 3/8. Cross multiply to get 15*8 = 3*x. Solving for x gives x=40. Choice A is correct because it correctly solves the proportion. Choices B, C, and D are incorrect as they do not yield the correct value of x when solving the proportion.

Question 4 of 5

How many pints are in 56 ounces?

Correct Answer: B

Rationale: To convert ounces to pints, we know that 1 pint is equal to 16 ounces. Therefore, to find how many pints are in 56 ounces, we divide 56 by 16, which equals 3.5 pints. Hence, the correct answer is B: 3.5 pints. A: 3 pints - Incorrect. 56 ounces is more than 3 pints. C: 7 pints - Incorrect. 56 ounces equals 3.5 pints, not 7 pints. D: 8 pints - Incorrect. 56 ounces is less than 8 pints.

Question 5 of 5

A vitamin's expiration date has passed. It was supposed to contain 500 mg of calcium, but it has lost 325 mg of calcium. How many mg of calcium are left?

Correct Answer: A

Rationale: The correct answer is A (175 mg). To find out how much calcium is left, subtract the lost amount (325 mg) from the original amount (500 mg): 500 mg - 325 mg = 175 mg. This calculation shows that 175 mg of calcium are left in the expired vitamin. Choice B (135 mg) is incorrect because it does not account for the correct subtraction of the lost amount. Choice C (185 mg) and Choice D (200 mg) are also incorrect as they do not reflect the accurate calculation based on the given information.
