Percentage Help Needed

[Esmée]

Hey,

I was wondering whether someone could explain to me how to calculate grade percentages. The degree is made up of three elements. These elements are worth 50%, 20% and 30% each.

For element 1 (which is worth 50%) I got:

63%, 61%, 61%, 61%

For element 2 (worth 20%) I got:

65% and 64%

For element 3 (worth 30%) I got:

42%, 58%, 64% and 62%

I need to obtain 50% in each element in order to pass my course. But I just cannot seem to figure out how to calculate whether I got above 50% in each element. I've been trying to calculate it myself, but I just cannot seem to figure it out
I'd be really thankful for any help!!!

From what I can see, for the first part you have an average of \(\displaystyle \frac{.63+.61+.61+.61}{4}=.615\)

Since this counts for 50%, then you have \(\displaystyle .50(.615)=\fbox{.3075}\)

The second part:

\(\displaystyle \frac{.65+.64}{2}=.63\)

\(\displaystyle .20(.63)=\fbox{.129}\)

3rd part:

\(\displaystyle \frac{.42+.58+.64+.62}{4}=.565\)

\(\displaystyle .30(.565)=\fbox{.1695}\)

Add them all up in the boxes and get a 60.6%.
