1. What is the boiling point of water?

• A. 100°C
• B. 98°C
• C. 99°C
• D. 102°C

Correct answer: A

Rationale: The correct answer is 100°C (Choice A). The boiling point of water is the temperature at which it changes from a liquid to a gas. Under normal atmospheric pressure, water boils at 100°C. Choices B, C, and D are incorrect because they do not represent the standard boiling point of water. 98°C, 99°C, and 102°C do not correspond to the temperature at which water boils under normal conditions.

2. Rewrite the following expression as a decimal: 5/8

• A. 0.7
• B. 0.325
• C. 0.625
• D. 5.8

Correct answer: C

Rationale: To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 5 ÷ 8 = 0.625. Therefore, the correct answer is 0.625. Choice A (0.7) is incorrect as it represents 7/10, choice B (0.325) is incorrect as it represents 325/1000, and choice D (5.8) is incorrect as it is not the result of dividing 5 by 8.

3. Solve: 2 - 8(24 ÷ 2).

• A. -94
• B. -92
• C. -96
• D. -90

Correct answer: A

Rationale: To solve the expression, we follow the order of operations (PEMDAS). First, we divide 24 by 2 to get 12. Then, we multiply 8 by 12, which equals 96. Finally, we subtract 96 from 2: 2 - 96 = -94. Therefore, the correct answer is A, '-94'. Choices B, C, and D are incorrect as they do not follow the correct order of operations or make errors during calculation.

4. Divide: 11 ÷ 5 =

• A. 1.424
• B. 1.622
• C. 2.2
• D. 2

Correct answer: C

Rationale: To divide 11 by 5, you need to perform the division operation. 11 divided by 5 equals 2.2. Therefore, the correct answer is C. Choice A (1.424) and Choice B (1.622) are incorrect as they do not result from the division of 11 by 5. Choice D (2) is close but not accurate, as the exact result of 11 divided by 5 is 2.2.

5. What is the value of pi (Ï€) to 2 decimal places?

• A. 3.12
• B. 3.14
• C. 3.16
• D. 3.18

Correct answer: B

Rationale: The value of pi (Ï€) up to two decimal places is 3.14. Pi is a mathematical constant representing the ratio of a circle's circumference to its diameter and is commonly approximated as 3.14. Choices A, C, and D are incorrect as they do not match the standard approximation of pi up to two decimal places.
