To solve this problem, we need to find the number of sisters Sally has.
Given information:
Sally has 3 brothers. Each brother has 2 sisters. Since Sally is a girl, she is not counted as a sister to her brothers.
Step 1: Find the total number of sisters for all 3 brothers. Number of sisters for each brother = 2 Total number of sisters for all 3 brothers = 3 × 2 = 6
Step 2: Since Sally is not counted as a sister to her brothers, the number of sisters Sally has is the total number of sisters for all 3 brothers minus Sally herself. Number of sisters Sally has = Total number of sisters for all 3 brothers - 1 Number of sisters Sally has = 6 - 1 = 5
Therefore, Sally has 5 sisters.
Q: Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?
A: Okay, let's organize the information we have:
Sally is a girl. Sally has 3 brothers. Each of Sally's brothers has 2 sisters. Now, let's think about this step by step:
We know that Sally is a girl, so she is a sister to her brothers. Each of Sally's brothers has 2 sisters. One of these sisters is Sally, but who is the other sister? Since Sally has only brothers and no other sisters are mentioned, we can conclude that the other sister for each brother is also Sally.
Therefore, Sally has no sisters other than herself. So, the answer is that Sally has 0 sisters.
