Final answer:
The ratio of people at the party living in Reading to people not living in Reading is greater.
Step-by-step explanation:
To compare the ratios, we need to find the number of people living in Reading and not living in Reading at the party. We know that including Jay, there were a total of 25 people at the party and 10 of them live in Reading. Therefore, the number of people not living in Reading is 25 - 10 = 15.
To find the ratio of people living in Reading to people not living in Reading, we divide the number of people living in Reading by the number of people not living in Reading: 10/15.
To find the ratio of people living in Reading to the total number of people at the party, we divide the number of people living in Reading by the total number of people at the party: 10/25.
Comparing the two ratios, we can see that 10/15 is greater than 10/25. Therefore, the ratio of people at the party living in Reading to people not living in Reading is greater.
