Question

A company conducted a survey to see whether its new toothpaste was more

popular with children or adults. Of the adults surveyed, about 11% use the
toothpaste. Compare this with the percentage of children who use the
toothpaste.

Answer 1

Answer: B. A greater percentage of children (28%) use the toothpaste

For each data value in the table, move the decimal point over 2 spots. We focus on the "children" row only since each answer choice has "of children" mentioned, and also the instructions make this mention as well. There are 7 children who use the toothpaste out of 25 children overall. So 7/25 = 0.28 = 28% of the children use the toothpaste. This is a greater percentage than the adults (11%) who use the toothpaste.

Note: the 11% comes from 8 adults out of 75 adults total who use the toothpaste, so 8/75 = 0.1067 = 10.67% which rounds to 11%
