Answer 1

There are approximately 88 adults.

Explanation:

The question is:

A fair was attended by 350 people of which two thirds are adolescents and a quarter adults and a fifth are children from 10 to 12 what amount corresponds to adults .

Solution:

Total number of people attending the fair is, N = 350.

The proportion of adults is: P (Adults) = p = 0.25.

Compute the number of adults in the fair as follows:

`\text{Number of adults in the fair}=N* p`

`=350* 0.25\\\\=87.5\\\\\approx 88`

Thus, there are approximately 88 adults.
