thirty percent of the 200 passengers sat alone.

1.Into how many parts were the passengers divided?
2. how many were in each part?
3.how many parts sat alone?
4. how many passengers sat alone?
5. how many parts did not sit alone?
6. how many passengers did not sit alone?

My same comments apply.

6. 120
4. 60

other questions depend on assumptions on the not sitting alone group, and how they were sitting.

To get the answers to these questions, we will break down the problem and calculate each part separately.

1. Into how many parts were the passengers divided?
To find the number of parts, we need to divide the total number of passengers by the percentage given. So, since 30% sat alone, the remaining 70% did not sit alone. Therefore, the passengers were divided into 2 parts.

2. How many were in each part?
To find the number of passengers in each part, we need to divide the total number of passengers by the number of parts. So, if there are 200 passengers divided into 2 parts, each part would have 200/2 = 100 passengers.

3. How many parts sat alone?
Since 30% of the passengers sat alone, this means that out of the 2 parts, only 1 part sat alone.

4. How many passengers sat alone?
To calculate the number of passengers who sat alone, we need to multiply the number of passengers in each part by the percentage who sat alone. So, if each part has 100 passengers and 30% sat alone, the number of passengers who sat alone would be 100 * 0.3 = 30 passengers.

5. How many parts did not sit alone?
Since there are 2 parts in total, and only 1 part sat alone, it means that 1 part did not sit alone.

6. How many passengers did not sit alone?
To calculate the number of passengers who did not sit alone, we need to subtract the number of passengers who sat alone from the total number of passengers. So, if there are 200 passengers and 30 passengers sat alone, the number of passengers who did not sit alone would be 200 - 30 = 170 passengers.
