Answer :
Ed's brother is the sum of both Ed and his sister's age, so Ed's brother is 6 + 3 = 9 years old.
To solve this problem, we can break it down step by step:
1. Given that Ed is 6 years old.
2. Since his sister is half his age, we divide Ed's age by 2 to find his sister's age: 6 / 2 = 3 years old.
3. The problem states that Ed's brother is the sum of Ed and his sister's age. So we add Ed's age (6) and his sister's age (3) together: 6 + 3 = 9 years old.
4. Therefore, Ed's brother is 9 years old.
