Correct Answer: B

Rationale: To find the number that 15 is 20% of, we set up the equation: x * 0.20 = 15. Solving for x, we get x = 15 / 0.20 = 75. Therefore, 15 is 20% of 75. Choice A, 3, is too small to be 20% of 15. Choice C, 75, is the result of the correct calculation. Choice D, 300, is too large to be 20% of 15.

Correct Answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: �C = (�F - 32) x 5/9. 2. Given that the patient's body temperature is 102�F, we can calculate the equivalent temperature in Celsius: �C = (102 - 32) x 5/9 �C = 70 x 5/9 �C = 350/9 �C ≈ 38.9�C, which can be rounded to 39�C. 3. A body temperature of 39�C is considered to indicate a fever. Normal body temperature typically ranges from 36.1�C to 37.2�C, so a temperature of 39�C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102�F to �C

Correct Answer: D

Rationale: If 20 students are divided into pairs, there would be 10 pairs in total (20 students / 2 = 10 pairs). Since each pair receives 10 pencils, the total number of pencils needed is calculated by multiplying the number of pairs (10 pairs) by the number of pencils each pair receives (10 pencils per pair), resulting in 100 pencils required. Therefore, the correct answer is 100 pencils. Choices A, B, and C are incorrect because they do not consider the correct pairing of students or the total number of pencils needed for each pair.

Correct Answer: A

Rationale: To find out how many ounces are in 4 cups, you need to multiply 8 ounces (the number of ounces in 1 cup) by 4 cups. This calculation results in 32 ounces. However, the question asks for the number of ounces in 4 cups, not the total ounces in 4 cups. Therefore, there are 16 ounces in 4 cups. Choices B, C, and D are incorrect as they do not represent the correct conversion of ounces in 4 cups.

Correct Answer: C

Rationale: To convert Fahrenheit to Celsius, you can use the formula:
