b. a greater percentage of children (40%) use the toothpaste.

c. a smaller percentage of children (6%) use the toothpaste.

d. a smaller percentage of children (8%) use the toothpaste.

Explanation:

Step1: Calculate children's usage percentage

The proportion of children who use the toothpaste is given as 0.06 (from the table). To convert this to a percentage, multiply by 100: \(0.06\times100 = 6\%\).

Step2: Compare with adults' percentage

Adults' usage percentage is about 11%. Since \(6\%<11\%\), children have a smaller percentage of using the toothpaste.

Answer:

C. A smaller percentage of children (6%) use the toothpaste.
