Final answer:
Samuel's statement about his sister's age being proportional to his brother's age depends on the specific ages and whether one is a constant multiple of the other. Without specific details, we can't say definitively if he is correct.
Step-by-step explanation:
To determine if Samuel's statement about his sister's age being proportional to his brother's age is true , we need to understand what proportional means. In mathematics, proportional refers to one quantity being a constant multiple of another. If Samuel's sister's age can be expressed as a constant multiple of his brother's age, then we can say that their ages are proportional.
For example, if Samuel's sister is 6 years old and his brother is 3 years old, we can see that her age is twice his age. In this case, the sister's age is proportional to the brother's age with a proportionality constant of 2. Without the specific ages or more information, we cannot definitively answer true or false, but we can say that it is possible for Samuel's statement to be correct under certain circumstances.
