Question 1 of 5

Express 0.9% as a decimal.

Correct Answer: A

Rationale: To convert a percentage to a decimal, divide by 100. In this case, 0.9% = 0.9 � 100 = 0.009. Therefore, the correct answer is A) 0.009, which represents 0.9% in decimal form.

Question 2 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 3 of 5

Convert 7/10 to a decimal.

Correct Answer: A

Rationale: To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 7 � 10 = 0.7. Dividing by 10 shifts the decimal point one place to the left, making the conversion straightforward. Therefore, the correct decimal form of 7/10 is 0.7.

Question 4 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 5 of 5

Ratio and Proportion: 0.5:20 :: X:200

Correct Answer: A

Rationale: To solve this proportion problem, you need to set up the ratio 0.5/20 equal to X/200. Cross-multiply to solve for X, which gives you 0.5 � 200 = 20X. Simplifying this, you get 100 = 20X, and then by dividing both sides by 20, you find that X = 5. Therefore, the correct answer is A, X = 50.
