We have $$\frac{1}{2}+\frac{\frac{2}{3}\cdot\frac{3}{8}}{4}-\frac{9}{16}$$
$$\frac{1}{2}+\frac{1}{16}-\frac{9}{16}$$
$$\frac{8}{16}+\frac{1}{16}-\frac{9}{16}$$
= 0

The correct answer: E

Hope this helps!

Simplifying, we have:

1/2 + (1/4)/4 - 9/16

1/2 + 1/16 - 9/16

Getting a common denominator of 16, we obtain:

8/16 + 1/16 - 9/16 = 0

Answer: E
