What temperature in Celsius is 98.6 degrees Fahrenheit?
- A. 30 Celsius
- B. 37 Celsius
- C. 47 Celsius
- D. 21 Celsius
Correct Answer: B
Rationale: To convert Fahrenheit to Celsius, you can use the formula: C = (F - 32) x 5/9. Substituting 98.6 for F: (98.6 - 32) x 5/9 = 37°C. Therefore, 98.6 degrees Fahrenheit is equivalent to 37 degrees Celsius.

What is the result of dividing 32 by 8/9?
- A. 36
- B. 4&1/9
- C. 28&4/9
- D. 4
Correct Answer: A
Rationale: To divide by a fraction, you multiply by its reciprocal. In this case, dividing 32 by 8/9 is the same as multiplying 32 by 9/8 (reciprocal of 8/9). Calculate 32 * 9/8 to get 36, which is the correct result. Therefore, the correct answer is A: 36. So, the correct answer is 36.
Round to the nearest percentage point: Gerald made 13 out of the 22 shots he took in the basketball game. What was his shooting percentage?
- A. 13%
- B. 22%
- C. 59%
- D. 67%
Correct Answer: C
Rationale: To calculate Gerald's shooting percentage, divide the number of shots made (13) by the total shots taken (22) to get the fraction of shots made. Then, multiply this fraction by 100 to convert it to a percentage. The calculation is (13/22) * 100 = 0.59 * 100 = 59%. Therefore, Gerald's shooting percentage is 59%, which corresponds to choice C.
If the quotient of X and 12 is 4, what is the divisor?
- A. X+12
- B. X-12
- C. 4
- D. 3
Correct Answer: C
Rationale: To find the divisor when the quotient of X and 12 is 4, we use the formula for division: Dividend = Divisor x Quotient. Given that the quotient is 4 and Dividend = X, we have X = 12 x 4 = 48. Therefore, the divisor is the number that, when multiplied by 4, equals 48, which is 12. So, the correct answer is C: 4.
Choice A (X+12) is incorrect because it represents adding X and 12 together, not the divisor.
Choice B (X-12) is incorrect because it represents subtracting 12 from X, not the divisor.
Choice D (3) is incorrect because it is not related to the given information about X and the quotient being 4.
What is the result of dividing 3.44 by 0.6?
- A. 11.41
- B. 5.73
- C. 2.33
- D. 0.57
Correct Answer: B
Rationale: To divide 3.44 by 0.6, align the decimal points by making the divisor a whole number: 3.44 · 0.6 = 3.44 · 0.60 = 5.73. Therefore, the correct answer is 5.73. When dividing decimal numbers, ensure the decimal points are aligned and then perform the division as if they were whole numbers. Adding a trailing zero to the dividend in this case makes the division easier and ensures the correct placement of the decimal point in the quotient. Remember, maintaining the alignment of decimal points is crucial to accurately dividing decimal numbers.
Compare the relationships of these numbers: 0.25 is _______ to 25%.
- A. equal
- B. greater
- C. less
- D. not comparable
Correct Answer: A
Rationale: 0.25 is equivalent to 25% because they represent the same value in different forms. 0.25 is the decimal representation of 25% (0.25 = 25/100), making them equal in value. When comparing these two numbers, they are not greater or lesser than each other; they are exactly the same amount, just expressed differently. Therefore, the correct answer is 'equal' as 0.25 and 25% are essentially the same numeric value in different formats, demonstrating an equal relationship between them.
