1. Multiply 0.05 by 22 and express the result as a decimal:

• A. 1.1
• B. 0.11
• C. 0.011
• D. 0.0011

Correct answer: C

Rationale: When multiplying 0.05 by 22, you get 1.10. To express this result as a decimal, you move the decimal point two places to the left since there are two total decimal places in the question (one in 0.05 and none in 22), resulting in 0.011. Choice A (1.1) incorrectly adds a decimal place, choice B (0.11) incorrectly moves the decimal point only one place, and choice D (0.0011) adds an extra zero.

2. A pizza has a diameter of 40cm. What is its perimeter (circumference)?

• A. 62.8cm
• B. 125.5cm
• C. 125.6cm
• D. 251.2cm

Correct answer: C

Rationale: Rationale: The correct answer is obtained by applying the formula for the circumference of a circle, which is \(C = \pi \times d\), where \(d\) is the diameter of the circle. By substituting the given diameter of 40cm into the formula and performing the calculation, we find that the circumference of the pizza is 125.6cm.

3. What is the result of adding 6 3/4 + 8 1/6?

• A. 14 & 11/12
• B. 12 & 3/24
• C. 35/6
• D. 14 & 2/5

Correct answer: A

Rationale: To add mixed numbers, first convert them to improper fractions. 6 3/4 = 27/4 and 8 1/6 = 49/6. Finding a common denominator, we get 27/4 + 49/6 = 81/12 + 98/12 = 179/12 = 14 & 11/12. Therefore, the correct answer is A. Choice B is incorrect as it does not simplify to the correct result. Choice C is in fraction form and not in mixed number form, making it incorrect. Choice D is not the correct sum of the given mixed numbers, so it is also incorrect.

4. A train travels at 80 mph for 3 hours. How far did it travel?

• A. 240 miles
• B. 160 miles
• C. 280 miles
• D. 320 miles

Correct answer: A

Rationale: To calculate the distance traveled, you multiply the speed of the train (80 mph) by the time it traveled (3 hours): 80 mph × 3 hours = 240 miles. Therefore, the correct answer is 240 miles. Choice B (160 miles) is incorrect because it results from multiplying the speed by the incorrect time. Choices C (280 miles) and D (320 miles) are incorrect as they represent calculations that do not match the given speed and time.

5. If a recipe requires 3 eggs for every pound of cake, how many pounds of cake can be made with 40 eggs?

• A. 12 pounds
• B. 14 pounds
• C. 13 pounds
• D. 15 pounds

Correct answer: C

Rationale: To determine the pounds of cake that can be made with 40 eggs, divide the total number of eggs by the eggs needed per pound of cake: 40 eggs ÷ 3 eggs/pound = 13 pounds of cake. Therefore, the correct answer is 13 pounds. Choice A, 12 pounds, is incorrect because it does not consider the ratio of eggs to cake. Choice B, 14 pounds, and Choice D, 15 pounds, are incorrect as they do not reflect the correct calculation based on the given ratio in the question.
