Both numerator and denominator are a sum of 51 terms, counted skipping 4s (numerator) and 2s (numerator).
So, you have
![\dfrac{\displaystyle\sum_{i=1}^{51} 4i}{\displaystyle\sum_{i=1}^{51} 2i}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Cdisplaystyle%5Csum_%7Bi%3D1%7D%5E%7B51%7D%204i%7D%7B%5Cdisplaystyle%5Csum_%7Bi%3D1%7D%5E%7B51%7D%202i%7D%20)
Use the linearity of sum to rewrite this as
![\dfrac{\displaystyle4\sum_{i=1}^{51} i}{\displaystyle2\sum_{i=1}^{51} i}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B%5Cdisplaystyle4%5Csum_%7Bi%3D1%7D%5E%7B51%7D%20i%7D%7B%5Cdisplaystyle2%5Csum_%7Bi%3D1%7D%5E%7B51%7D%20i%7D%20)
So, as you can see, the numerator is exactly twice the numerator: you can cancel out the sum and you have
![\dfrac{4}{2} = 2](https://tex.z-dn.net/?f=%20%5Cdfrac%7B4%7D%7B2%7D%20%3D%202%20)
Area is length times width. Therefore, width is area divided by length. Convert 11 7/8 to the improper fraction 95/8 and convert 4 3/4 to 19/4. Then, you can fine 95/8 divided by 19/4 by flipping the second fraction and multiplying so that you have 95/8 times 4/19. 4 times 95 is 380 and 8 times 19 is 152. Therefore, the answer is 380/152. This is equivalent to 5/2 or 2.5.

Answer:
44.44%
Step-by-step explanation:
- 360-200=160
