To divide 1/2 by 4, you can treat it as (1/2)/(4/1), and to divide fractions you flip the second fraction and multiply, so:
(1/2)*(1/4)=1/8
So each portion of chocolate was 1/8 pounds.
The formula for area of a trapezoid is:

Sides a is the top line and side b is the base, or bottom line. Add the sides together and divide by 2. After you do that, multiply the answer by the height.
Height is the length between the two sides, a and b.
If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.
Example 1:

Here, since the numerator is a fraction, it is a complex fraction.
Example 2:

Here, since the numerator and the denominator are fractions, it is a complex fraction.
