To determine how many sisters Sally has, we start by analyzing the information provided in the question:
"Sally (a girl) has 3 brothers. Each brother has 2 sisters. How many sisters does Sally have?"
Step 1: Understand the Family Composition
- Sally is a girl.
- She has 3 brothers, which means there are 3 male siblings in the family.
- The key phrase is: "Each brother has 2 sisters."
This tells us that from the perspective of each brother, there are 2 female siblings in the family.
Step 2: Interpret the Meaning of "Each Brother Has 2 Sisters"
- Since Sally is one of the girls in the family, and each brother has 2 sisters, that means there are 2 girls in total in the family.
- One of those girls is Sally, and the other is her sister.
So, the family consists of:
- 3 boys (Sally's brothers),
- 2 girls (Sally and her one sister).
Step 3: Answer the Question
The question is: "How many sisters does Sally have?"
- Sally is a girl, so she doesn't count herself as her own sister.
- There is one other girl in the family — her sister.
Thus, Sally has 1 sister.
Final Answer
$$ \boxed{1} $$
GPT-4.1
Let's break down the problem:
- Sally is a girl.
- She has 3 brothers.
- Each brother has 2 sisters.
Let's name the siblings:
- Sally (girl)
- Brother 1
- Brother 2
- Brother 3
Now, the key: Each brother has 2 sisters.
Since Sally is one of the sisters, let's see if there are more:
Suppose there is only one girl (Sally) in the family.
- Then each brother would have only 1 sister: Sally.
- But the problem says they have 2 sisters each.
Thus, Sally must have one sister (since the brothers must have 2 sisters). Let's call this other sister "Anna".
So the siblings are:
- Sally (girl)
- Anna (girl)
- Brother 1
- Brother 2
- Brother 3
Now, each brother has 2 sisters: Sally and Anna.
So, how many sisters does Sally have?
- Sally's sisters = 1 (Anna).
Final Answer:
Sally has 1 sister.

To determine whether 9.11 is greater than 9.9, we need to compare the two decimal numbers carefully.
Step 1: Align the Numbers
To make the comparison clear, we can express both numbers with the same number of decimal places:
- 9.11 (already has two decimal places)
- 9.9 → 9.90 (adding a zero to match decimal places)
Now we have:
9.11
9.90
Step 2: Compare Digit by Digit
Start from the leftmost digit and move right:
- Units place: Both numbers have 9 → equal.
- Tenths place: 1 vs 9 → 9 > 1
Since 9 > 1 in the tenths place, we can conclude that 9.90 > 9.11, and thus 9.9 > 9.11.
Step 3: Alternative Verification (Optional)
To double-check, we can:
- Multiply both numbers by 100 to eliminate decimals:
- 9.11 × 100 = 911
- 9.9 × 100 = 990
Now compare the integers: 990 > 911, confirming that 9.9 > 9.11.
Final Conclusion
Since 9.9 > 9.11, the statement "Is 9.11 greater than 9.9?" is false.
$$ \boxed{No} $$
GPT-4.1
No, 9.11 is not greater than 9.9.
Here's why:
- 9.11 is actually less than 9.9.
Let's compare:
- 9.9 is equal to 9.90 (adding a zero for easier comparison).
- 9.11 < 9.90
So, 9.11 < 9.9.
