Answer: 1161

Step-by-step explanation:

From the question, ww are told that 1935 people visit a library during one week and the ratio of children to adult is 1:4.

This means that the fraction of children is 1/5 qnd the fraction of adult is 4/5. Since there are 1935 people, the number of children will be:

= 1/5 × 1935

= 387

The number of adults will be:

= 4/5 × 1935

= 1548

To find the number of more adults than children that visited the library, we subtract 387 from 1548. This will be:

= 1548 - 387

= 1161
