Ok so to start you can go ahead and multiple $4.50 by 6 because she is buying 6 books.
4.5*6 = 27
So subtract 27 from 39
39-27=12
Divide 12 by .25
12/.25 = 48
Now divide 48 pieces amount her 6 friends
48/6 =8
8 pieces for each of her friends

4.50 x 2 x 3 = 27
39 - 27 = 12
12 / .25 = 48
48 candies total
8 pieces each
48 / 6 = 8
