Question 2 of 5
A new mother changes her baby's diaper 6 times a day, on average. How many diapers will the child use in a year?
Correct Answer: A
Rationale: To calculate the total number of diapers used in a year, you need to multiply the daily diaper changes (6 diapers) by the number of days in a year (365): 6 � 365 = 2,190. Therefore, the correct answer is 2,190 diapers.
Question 3 of 5
How many ounces (oz) are in 3/4 pint?
Correct Answer: B
Rationale: To convert 3/4 pint to ounces, you need to know that 1 pint is equal to 16 ounces. To find out how many ounces are in 3/4 pint, you multiply 3/4 by 16. This calculation gives us 12 ounces. Therefore, there are 12 ounces in 3/4 pint. Remember, when converting between different units of measurement, it is crucial to understand the relationship between the two units to perform accurate conversions.
Question 4 of 5
Convert 5 3/4 to a decimal. Round to the nearest tenth.
Correct Answer: A
Rationale: To convert a mixed number to a decimal, divide the numerator by the denominator. In this case, 3 � 4 = 0.75. Adding this to 5 gives us 5.75. Rounding 5.75 to the nearest tenth results in 5.8. Therefore, the correct answer is A, 5.8.
Question 5 of 5
Multiply: 2/3 x 3/5 =
Correct Answer: C
Rationale: To multiply fractions, multiply the numerators and the denominators: (2 x 3) / (3 x 5) = 6/15. Simplifying gives 2/5. Thus, the correct answer is C) 2/5.
