The teacher has 48 fiction books and 36 non-fiction books.

1) 4*12=48 3*12=36
2) 48+36=84
3)4:3 = 48:36

Since the ratio is 4:3, you can set the equation 7x = 84
and 4x = fiction, 3x = nonfiction.
x=12

so there are 48 fiction and 36 nonfiction

Answer: 4 Cups

I think in order to solve this, you would need to add up the fractions that they used. So it would be,

$\frac{1}{4}+\frac{1}{4}+\frac{3}{8}+\frac{3}{8}+\frac{5}{8}+\frac{5}{8}+\frac{5}{8}+\frac{7}{8}$ Transform the Expressions

$\frac{1+1}{4} +\frac{3+3+5+5+5+7}{8}$ Calculate the sum

$\frac{2}{4} +\frac{28}{8}$ Reduce

$\frac{1}{2}+\frac{7}{2}$ Transform the Expression

$\frac{1+7}{2}$ Calculate

$\frac{8}{2}$ Reduce the Fraction

$4$
