- A. 400 miles
- B. 100 miles
- C. 320 miles

If a caregiver changes their baby 6 times a day, how many diapers will be needed in a year?
- A. 2160 diapers
- B. 2100 diapers
- C. 2190 diapers
- D. 6000 diapers
Correct Answer: C
Rationale: To determine the total number of diapers needed in a year, multiply the number of diaper changes per day (6) by the number of days in a year. Therefore, 6 diaper changes per day * 365 days per year = 2190 diapers. Hence, 2190 diapers will be needed in a year to keep up with the 6 diaper changes per day.
What is the result of adding 1/4 + 3/8?
- A. 4/12
- B. 1/3
- C. 5/8
- D. 1/2
Correct Answer: C
Rationale: To add fractions, a common denominator is needed. In this case, the common denominator is 8. Converting 1/4 to have the same denominator results in 2/8. Adding 2/8 + 3/8 gives 5/8. Thus, the correct answer is 5/8.
15:3 = x:5. Find the value of x. (Enter whole number only.)
- A. 20
- B. 25
- C. 30
- D. 35
Correct Answer: B
Rationale: To find the value of x, we can set up a proportion: 15/3 = x/5. Simplifying this, we get 5 = x/5. Multiplying both sides by 5 gives us x = 25. Therefore, the correct answer is B (25). Choice A (20) is incorrect because it does not satisfy the proportion. Choices C (30) and D (35) also do not fit the proportion and are therefore incorrect options.
