Answer 2

43.75% students were participated last year.

Explanation:

We have been given that last year 7/16 of all students at a school participated in the science fair.

Let us suppose the total number of students were x. Then, number of students participated last year is given by

`(7)/(16) x`

Hence, the percentage of the students participated last year is given by

`\%=((7)/(16)x )/(x) * 100\\\\\%=(7)/(16)* 100\\\\\%=43.75\%`

Therefore, 43.75% students were participated last year.
