Express the ratio of 25:80 as a percentage.
- A. 31.25%
- B. 34%
- C. 41.25%
- D. 43.75%
Correct Answer: A
Rationale: To express the ratio 25:80 as a percentage, follow these steps: First, divide 25 by 80: 25/80 = 0.3125. Then, multiply by 100 to convert to a percentage: 0.3125 100 = 31.25%. Therefore, the ratio 25:80 is equivalent to 31.25%. Choice A is correct. Choice B (34%) is incorrect because it does not accurately represent the ratio 25:80. Choice C (41.25%) and Choice D (43.75%) are also incorrect as they do not match the calculated percentage for the given ratio.
Multiply: 5.04 2 =
- A. 1.008
- B. 10.08
- C. 10.8
- D. 18
Correct Answer: B
Rationale: To multiply 5.04 by 2, you simply multiply the two numbers together: 5.04 x 2 = 10.08. Therefore, the correct answer is B. Choice A (1.008) is incorrect as it represents the result of dividing 5.04 by 5 instead of multiplying. Choice C (10.8) is incorrect as it is the result of rounding 10.08 to the nearest whole number. Choice D (18) is incorrect as it results from adding 5.04 and 2 instead of multiplying.
Temperature Conversion & Interpretation: A patient's body temperature is 102°F. Convert this to °C and assess if it indicates a fever.
- A. 37°C (Normal)
- B. 39°C (Low-grade fever)
- C. 39°C (Fever)
- D. 42°C (Hyperthermia)
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
A gross is equal to 12 dozen. If Lanyard Farms sells 15 gross of eggs a week and packages them in one dozen egg containers, how many containers do they need for a week's worth of eggs?
- A. 15
- B. 150
- C. 180
- D. 2,160
Correct Answer: C
Rationale: Given that a gross is equal to 12 dozen, 15 gross of eggs would be equal to 15 * 12 = 180 dozen eggs. Since the eggs are packaged in one dozen egg containers, Lanyard Farms would need 180 containers for a week's worth of eggs. Choice A (15) is incorrect as it represents the number of gross, not containers. Choice B (150) is incorrect as it miscalculates the total number of containers needed. Choice D (2,160) is incorrect as it overestimates the number of containers required.
Multiply: 6 0.06 =
- A. 0.0036
- B. 0.036
- C. 0.36
- D. 3.6
Correct Answer: C
Rationale: When multiplying 6 by 0.06, you can treat 0.06 as 6 hundredths. So, 6 0.06 is equivalent to 6 6 hundredths, which equals 0.36. The correct answer is 0.36. Choice A (0.0036) is incorrect because it represents 6 multiplied by 0.0006, not 0.06. Choice B (0.036) is incorrect as it represents 6 multiplied by 0.06 without considering the position of the decimal point. Choice D (3.6) is incorrect as it represents 6 multiplied by 6, not by 0.06.
