To determine how many sisters Sally has, we can break down the information given in the problem step by step.

Identify the number of brothers Sally has. According to the problem, Sally has 3 brothers.
Each of Sally's brothers has 2 sisters. Since Sally is one of the sisters, the other sister must be the same for all brothers. Therefore, the other sister is the same person, not a different sister for each brother.

Let's denote the sisters as follows:

Sally is one sister.
Let's call the other sister ( S ).

Since each brother has 2 sisters and Sally is one of them, the other sister must be ( S ). This means that Sally and ( S ) are the only two sisters.

Thus, Sally has 1 sister.

The answer is (\boxed{1}).

I need to think through this step-by-step.

Given information:

Sally is a girl
Sally has 3 brothers
Each brother has 2 sisters

Let me work out how many sisters are in the family total.

If each of Sally's 3 brothers has 2 sisters, and all the brothers are in the same family, then there must be 2 sisters total in the family.

Since Sally is one of those sisters, and there are 2 sisters total, Sally must have 1 sister.

Therefore, Sally has 1 sister.

No, 9.11 is not greater than 9.9.

To compare these decimal numbers:

9.11 = 9.11
9.9 = 9.90

Since both numbers have the same whole number part (9), we compare the decimal parts:

0.11 vs 0.90
11 hundredths vs 90 hundredths

Therefore, 9.9 is greater than 9.11.
