Final answer:
Yes, the numbers of people in rooms can form a proportion.
Step-by-step explanation:
Yes, the numbers of people in rooms can form a proportion.
A proportion is a statement that two ratios are equal. In this case, the ratio of the number of people in one room to the number of people in another room can be written as a fraction, such as 3/5. If this ratio is equal to the ratio of the number of people in two other rooms, then it forms a proportion.
For example, if there are 3 people in one room and 5 people in another room, and there are 9 people in a third room and 15 people in a fourth room, the two ratios of people in rooms are equal: 3/5 = 9/15. Therefore, the numbers of people in rooms form a proportion.
