Answer:
![-\frac{1}{32}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B32%7D)
Step-by-step explanation:
![n = 8\\1/2(8) - 3/4(8) = 1/16-3/32](https://tex.z-dn.net/?f=n%20%3D%208%5C%5C1%2F2%288%29%20-%203%2F4%288%29%20%3D%201%2F16-3%2F32)
Multiply the numerator and denomiator of 1/16 by 2 so that the denominators are equal and we can subtract.
![\frac{1}{16} *\frac{2}{2} =\frac{2}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B16%7D%20%2A%5Cfrac%7B2%7D%7B2%7D%20%3D%5Cfrac%7B2%7D%7B32%7D)
Then, subtract
![\frac{2}{32} -\frac{3}{32} = \frac{2-3}{32} =- \frac{1}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B32%7D%20-%5Cfrac%7B3%7D%7B32%7D%20%3D%20%5Cfrac%7B2-3%7D%7B32%7D%20%3D-%20%5Cfrac%7B1%7D%7B32%7D)
B involves direct variation.
y and x are directly proportional.
