The first question is 1.5
We get that by dividing the amount of coco (6) but the number of cups (4)
The second answer is 4/6 or .666666
We get that but dividing 4 by 6
e is the Exponential Constant or Euler's Number.
It has a value of <u>2.718281828... </u>

e to the n is given by:
![\huge{e}^{n}= [\sum_{k=0}^{∞} (\frac{{n}^{k}}{k!})]](https://tex.z-dn.net/?f=%5Chuge%7Be%7D%5E%7Bn%7D%3D%20%5B%5Csum_%7Bk%3D0%7D%5E%7B%E2%88%9E%7D%20%28%5Cfrac%7B%7Bn%7D%5E%7Bk%7D%7D%7Bk%21%7D%29%5D)
84(1/7)+9(1/3)
The 84 is divided by the 1/7th and the 9 is divided by the 1/3. They are then added.
The missing angle is 32°.
