What is 54% of $789.56?
- A. $426.37
- B. $363.20
- C. $426.36
- D. $526.38
Correct Answer: C
Rationale: To find 54% of $789.56, you need to multiply $789.56 by 0.54 (which represents 54% as a decimal). $789.56 * 0.54 = $426.36. Therefore, the correct answer is $426.36. When calculating a percentage of a number, you convert the percentage to a decimal by dividing by 100 (54% = 54/100 = 0.54) and then multiply it by the number to find the result. In this case, converting 54% to a decimal gives 0.54, and then multiplying by $789.56 gives the answer of $426.36.

What is the temperature in Fahrenheit when converted from 50°C? (Enter a numeric value only. If rounding is necessary, round to the nearest whole number.)
- A. 150°F
- B. 122°F
- C. 120°F
- D. 145°F
Correct Answer: B
Rationale: To convert Celsius to Fahrenheit, you can use the formula: F = (C — 9/5) + 32. Plugging in 50°C gives us (50 — 9/5) + 32 = 122°F. Therefore, the correct answer is 122°F. When converting temperatures between Celsius and Fahrenheit, it's important to remember the formula and apply it correctly. In this case, by substituting 50°C into the formula, it results in 122°F when rounded to the nearest whole number.
Convert 2100 to standard time =
- A. 9:00 PM
- B. 2:00 AM
- C. 2:00 PM
- D. 12:00 PM
Correct Answer: A
Rationale: To convert military time to standard time, subtract 12 hours if the time is after 12:00 PM. In this case, 2100 - 1200 = 900, which is equivalent to 9:00 PM in standard time notation. Remember that military time uses a 24-hour clock, where 2100 hours is equivalent to 9:00 PM in standard time format. Therefore, the correct answer is 9:00 PM.
Convert the percentage to a decimal: 126% =
- A. 126
- B. 0.0126
- C. 0.126
- D. 1.26
Correct Answer: D
Rationale: To convert a percentage to a decimal, you move the decimal point two places to the left. Therefore, 126% = 1.26 as a decimal. When you see 126%, it signifies having 126 parts out of 100, which is equivalent to 1.26 as a decimal. Remember that percentages represent parts out of 100, so converting to a decimal entails dividing by 100, resulting in the shift of the decimal point two places to the left.
Divide: 1 1/2 divided by 2 =
- A. 0.75
- B. 1
- C. 1.33
- D. 0.5
Correct Answer: A
Rationale: To divide 1 1/2 by 2, first convert 1 1/2 to an improper fraction: 3/2. Now, divide 3/2 by 2: 3/2 ÷ 2 = 3/2 x 1/2 = 3/4 = 0.75. Therefore, the correct answer is A (0.75). Choice B (1) is incorrect as the result is less than 1. Choice C (1.33) is incorrect as it is greater than 1. Choice D (0.5) is incorrect as it is the result of dividing 2 by 4, not 1 1/2 by 2.
If a label states that 1 mil contains 500 mg, how many mils are there if there are 1.5 grams?
- A. 2
- B. 5
- C. 9
- D. 3
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.
