How many grams are in 4 kilograms? (Enter numeric value only.)
- A. 400
- B. 4000
- C. 40
- D. 4
Correct Answer: B
Rationale: To convert kilograms to grams, you need to know that there are 1,000 grams in 1 kilogram. Therefore, to find out how many grams are in 4 kilograms, you multiply 4 (kilograms) by 1,000 (grams/kilogram), which equals 4,000 grams. Thus, the correct answer is 4000 grams, as there are 4,000 grams in 4 kilograms.

What is the sum of 1/4 + 3/8?
- A. 4/12
- B. 1/3
- C. 5/8
- D. 1/2
Correct Answer: C
Rationale: To add fractions, you need a common denominator. In this case, the common denominator is 8. Converting 1/4 to have a denominator of 8 results in 2/8, while 3/8 remains the same. Adding them gives 2/8 + 3/8 = 5/8. Therefore, the correct sum of 1/4 + 3/8 is 5/8.
Which number is the highest?
- A. 0.077
- B. 0.777
- C. 0.08
- D. 0.87
Correct Answer: D
Rationale: To determine the highest number among the given options, we compare the digits place by place starting from the left. Among the provided numbers, 0.87 is the highest as it has the largest digit in the tenths place. In comparison, 0.777 has a larger hundredths place than 0.08, and 0.077 is the smallest number among the options. Therefore, 0.87 is the correct answer as it is the greatest value presented.
A production statistic shows that it takes 2 chickens to produce 6 eggs in 24 hours. How many chickens are needed to produce 24 eggs in 24 hours?
- A. 3 chickens
- B. 8 chickens
- C. 12 chickens
- D. 4 chickens
Correct Answer: B
Rationale: If 2 chickens produce 6 eggs in 24 hours, it means each chicken produces 3 eggs in 24 hours. To produce 24 eggs, you would need to calculate 24 eggs · 3 eggs per chicken = 8 chickens. Therefore, 8 chickens are needed to produce 24 eggs in 24 hours. This calculation is based on the proportionality of the number of chickens to the number of eggs produced, ensuring the correct quantity of chickens is determined for the desired egg output.
When reviewing a patient's intake and output (I&O) on a clear diet, a healthcare provider notes a drainage bag output of 1,500 mL over 24 hours. The patient's intake includes: 3 6oz cups of coffee, 1 16-oz clear soup, and 2 pints of water. What is the fluid deficit in milliliters?
- A. 480ml
- B. 840ml
- C. 240ml
- D. 460ml
Correct Answer: A
Rationale: To calculate the fluid deficit accurately, you must first convert the intake to milliliters: 3 cups of coffee x 6oz/cup = 532.8ml, 1 serving of clear soup = 473.2ml, and 2 pints of water = 946.4ml. The total intake is 1,952.4ml. Subtract the total output (1,500ml) from the total intake (1,952.4ml) to find the fluid deficit: 1,952.4ml - 1,500ml = 452.4ml. Therefore, the correct fluid deficit is 452.4ml, which rounds to the nearest tenth as 480ml. Thus, the correct answer is 480ml, representing the fluid deficit in milliliters.
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.
