Answer 1

Answer:

Total students = 45

No. of students absent = 4 × 45 = 4 × 3 = 12 students

                                         15 (cancel 15 and 45)

So 12 students were absent on that day

Hope this helps :)

Answer 2

Explanation:

Given,

Total no. of students in school = 45

and 4/15 students were absent.

No of absent students= 45×4/15 =12 students

So, No of present students = 45 - (45 ×4/15)

=45 - 12 = 33 student
