Answer:
1/3 of the students
Step-by-step explanation:
4/12 of the students wins the small prize
so, 8/12 of the students will not get a small prize
1/2 of 8/12 = 4/12 = 1/3
1/3 of the students will get the certificate.
for a number its 4 because you do 12-4 since 4 will win the small prize so now there is 8 students left and the you divide 8 by 2 since half get a certificate and that gets you 4
