There are 32 students in the classroom
No. of student that completed there homework = 5/8 of 32
= 5/8 x 32
=20
No. of student that did not complete their homework = 1/4 of 32
=1/4 x 32
=8
we were told the rest lost theie homework
Hence, number of student that lost their homework = 32-20-8 = 4
Therefore, 4 students lost their work.
