Question 1 of 5
A parent is planning a birthday party for their child and wants to give each child 15 balloons. How many packets are needed for 16 children?
Correct Answer: B
Rationale: To find the total number of balloons needed, multiply the number of children by the number of balloons per child: 15 balloons x 16 children = 240 balloons. Since each packet contains 50 balloons, divide the total balloons needed by the balloons per packet: 240 balloons � 50 balloons per packet = 4.8 packets. As we cannot have a fraction of a packet, round up to the nearest whole number, which is 5 packets. Therefore, 5 packets are needed for 16 children to have 15 balloons each at the birthday party.
Question 2 of 5
Subtract: 9/12 - 3/12
Correct Answer: B
Rationale: To subtract fractions with the same denominator, subtract the numerators. In this case, 9/12 - 3/12 = (9-3)/12 = 6/12. Then, simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 6. Thus, 6/12 simplifies to 1/2.
Question 3 of 5
Which of the following decimals is the largest?
Correct Answer: D
Rationale: To determine the largest decimal among the options, you need to compare them by looking at the digits after the decimal point. When comparing 0.6, 0.667, 0.0688, and 0.68, consider that 0.6 is equivalent to 0.600, 0.667 remains 0.667, 0.0688 is already in its most precise form, and 0.68 is the same as 0.680. By comparing them, you can see that 0.68 is the largest decimal among the options provided. Remember, when comparing decimals, it's important to line up the decimal points to make accurate comparisons.
Question 4 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 5 of 5
Ratio and Proportion: 4:10 :: 5:X
Correct Answer: C
Rationale: To solve for X in the given ratio and proportion, set up the proportion: (4/10) = (5/X). Cross-multiply to get 4X = 50, leading to X = 12.5. So, the correct answer is X = 12.5, making choice C the correct option.
