Question 1 of 5
A school district has a student population of 6,734 students. If the maximum class size is 25 students, how many teachers must the district hire to supplement their current staff of 217 teachers?
Correct Answer: C
Rationale: To calculate the number of additional teachers needed, first determine the total number of classes by dividing the total student population by the maximum class size: 6734 students � 25 students = 269.36, rounded up to 270 classes. Then subtract the current number of teachers from the total classes to find the additional teachers required: 270 classes - 217 current teachers = 53 additional teachers needed.
Question 2 of 5
If a label states that 1 mil contains 500 mg, how many mils are there if there are 1.5 grams?
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.
Question 3 of 5
What is the result of adding 2/3 and 4/9?
Correct Answer: A
Rationale: To add 2/3 and 4/9, you need to find a common denominator. In this case, the common denominator is 9. Convert 2/3 to 6/9. Now, the addition becomes 6/9 + 4/9 = 10/9. Simplifying 10/9 gives you 1 (1/9). Therefore, the correct answer is 1 (1/9). When adding fractions, having a common denominator is essential for accurate calculation.
Question 4 of 5
A die is rolled. What is the probability of getting a 5?
Correct Answer: C
Rationale: The probability of rolling a specific number on a fair six-sided die is calculated by taking the total number of favorable outcomes (which is 1 in this case, as there is only one face with a 5) divided by the total possible outcomes (which is 6 for a standard die). Therefore, the probability of rolling a 5 is 1/6, which is approximately 16.6%. To convert the probability to a percentage, you multiply the fraction by 100, giving you 16.6%. Hence, the correct answer is C, 16.60%.
Question 5 of 5
In a class of 25 students, 44% are boys. How many boys are there?
Correct Answer: B
Rationale: To find the number of boys in the class, we first calculate 44% of 25 students. 44% of 25 is 0.44 x 25 = 11 boys. Therefore, there are 11 boys in the class.
