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 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

Change 0.004 to a ratio.

Correct Answer: C

Rationale: To convert 0.004 to a ratio, you first express it as a fraction, which is 4/1000. Simplifying this fraction gives 1/250. Therefore, the correct ratio for 0.004 is 1:250. This ratio represents the relationship between the parts, where for every 1 unit in the first part, there are 250 units in the second part. It's essential to simplify fractions to their lowest terms to express the ratio in its simplest form.

Question 4 of 5

Convert 0.60 to a ratio in simplest form.

Correct Answer: A

Rationale: To convert 0.60 to a ratio, start by expressing it as a fraction: 0.60 = 60/100. Then simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 20 in this case. Dividing 60 by 20 gives 3, and dividing 100 by 20 gives 5. Therefore, the simplified fraction is 3/5, which translates to the ratio 3:5 in simplest form.

Question 5 of 5

Subtract: 9/12 - 3/12

Correct Answer: B

Rationale: To subtract fractions with the same denominator, subtract the numerators. In this case, 9/12 - 3/12 = (9-3)/12 = 6/12. Then, simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 6. Thus, 6/12 simplifies to 1/2.
