Answer:

A. 8 students

B. Because 24% of 24 is 5.76

Step-by-step explanation:

A:  The ratio of students is 2:5, that means for every 7 students from her class, 2 of them are in the show.  

   28/7 is 4, so there are 2(4) = 8 students in the talent show.

B:  24(24%) = 24(0.24) = 5.76.  The question says 'exactly' 24%.  We can't have 0.76 of a person, so we can't have 'exactly' 24%
