15\25 + 42\52 = ?
Correct Answer: A
Rationale: 15\25 + 42\52 simplifies to 1 3\10.
Question 2 of 5
Edie has 132 tulip bulbs. She wants to plant all of the tulip bulbs in 12 rows. How many bulbs should she plant in each row?
Correct Answer: A
Rationale:
To plant 132 bulbs in 12 rows, Edie should plant 11 bulbs in each row. This is calculated by dividing the total number of bulbs by the number of rows: 132 bulbs · 12 rows = 11 bulbs per row.
Choice B, 10 bulbs, is incorrect because dividing 132 bulbs by 12 rows does not equal 10.
Choice C, 12 bulbs, is incorrect because if Edie plants 12 bulbs in each row, the total number of bulbs planted would exceed 132.
Choice D, 15 bulbs, is incorrect as dividing 132 bulbs by 12 rows does not result in 15 bulbs per row.
Question 3 of 5
The head nurse at the hospital has a team of six nurses and one phlebotomist. If the phlebotomist is responsible for 1/7 of the patients, what fraction of the patients is each nurse responsible for?
Correct Answer: A
Rationale: The correct answer is A: 1/6. The phlebotomist is responsible for 1/7 of the patients, leaving 6/7 of the patients for the six nurses.
To find out the fraction of patients each nurse is responsible for, divide the remaining patients (6/7) among the six nurses. This results in each nurse being responsible for 1/6 of the patients.
Choice B, 1/7, is incorrect because that is the fraction assigned to the phlebotomist.
Choices C and D, 1/8 and 1/5, are incorrect fractions and do not reflect the correct distribution of patients among the nurses.
Question 4 of 5
A physician wants to prescribe 5 mg of a medication to a patient. The medication comes in a 2-mg dose per 1-mL vial. How many milliliters of the medication should the patient receive?
Correct Answer: A
Rationale:
To determine the amount of medication the patient should receive, divide the prescribed dose by the dose per mL in the vial. In this case, 5 mg · 2 mg/mL = 2.5 mL.
Therefore, the patient should receive 2.5 mL of the medication.
Choice B (2 mL) is incorrect because it does not reflect the correct calculation.
Choice C (3 mL) is incorrect as it is higher than the actual amount calculated.
Choice D (1 mL) is incorrect as it is lower than the actual amount calculated.
Question 5 of 5
Alan is making a table. The table will be 6 1/2 feet long and 4 feet wide. The board for the table is 7 7/8 feet long and 4 feet wide. How much of the board will Alan need to cut off?
Correct Answer: A
Rationale:
To determine how much board Alan needs to cut off, subtract the length of the table from the length of the board: 7 7/8 - 6 1/2 = 1 3/8.
Therefore, Alan needs to cut off 1 3/8 feet from the board.
Choice A is correct.
Choice B (2) is incorrect because the subtraction result is 1 3/8, not 2.
Choice C (7/8) is incorrect as it represents only the fraction part of the answer, not the whole amount.
Choice D (3/4) is incorrect as it is a different fraction value than the result of the subtraction.
