The answer will be the biggest number, by which you can divide both 28 and 32. So you can divide them in 4 groups (28/4=7 girls per group & 32/4=8boys per group)
Check the picture below.
make sure your calculator is in Degree mode.
X = 9
y = 6
Step by step:
Divide 15 by 2: 15 ÷ 2 = 7.5
Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)
