Surely, I can help with that. Firstly, let's understand what the given information tells us.

- The wording "A girl has just as many sisters as brothers" implies that the number of sisters and brothers is equal. Let's call them 'b' for brothers and 's' for sisters.
- The next statement "But each of her brothers have only half as many sisters" means that for each brother, the number of sisters is half the number of brothers. That is, b is greater than or equal to 2s.

Now, to answer the question, let's equate them to make it simpler.

- b = s (according to the first sentence)
- b = 2s (according to the second sentence)

We can solve by substituting 's' in the second equation with 'b/2' from the first statement.

So, b = 2b/2 = b. The equation becomes b = b, which is true for any non-zero value of b.

Therefore, the number of brothers (b) and sisters (s) in the family can be anything, either 0, 1, 2, 3, or any number. The second statement could mean that each brother has half the sisters he has. For instance, if there are two brothers and both have three sisters, then the total number of siblings (brothers + sisters) would be 2 + 3 + 3 = 8.

However, it's essential to understand that this is a mathematical approach to the statement, and it's also possible that it's illogical or ambiguous.

Let's break this down:

1. If a girl has as many sisters as brothers, then for every brother she has, there is a corresponding sister. This implies that the number of brothers is equal to the number of sisters.

2. However, each of her brothers have only half as many sisters as they have brothers. This means that the number of sisters is half the number of brothers.

From these two points, we can deduce that each brother must have one sister. This is because if there were two or more sisters, the number of sisters would be equal to or greater than the number of brothers, not half.

So, each boy has one sister and each girl has one brother. Therefore, there must be two children in the family - one boy and one girl.

Final answer: There is one brother and one sister in the family.
