Answer 1

30 students

Explanation:

Given

`Students = 40`

`\% = 75\%` ---- percentage of those that returned their slips

Required

Determine the number of those that returned their slips

Represent the number with n

To calculate n, we simply multiply the number of students by the percentage of those that returned their slips

i.e.

`n = 40 * 75\%`

Convert % to decimal

`n = 40 * 0.75`

`n = 30`

Hence, 30 students returned their slips
