Question

If my final is 20% of the lecture grade, and the lecture grade is 60% of the overall grade, how much is the final worth overall?

If quizzes are worth 10% of the lecture grade, and the lecture is 60% of the overall grade, how much are each of the four quizzes overall? Is the number different if you figure each quiz is 2.5% of the 60% versus all four quizzes being 10% of the 60%?

I hope that makes sense... I'm sure I'm wording it strangely.

I'm not really concerned about what I have to make, I have an idea about that. I want to know how to solve this because I have an app that lets you weigh each category but it doesn't let you separate grades within one class into lab (which is 40% of the overall grade) and lecture grades (60% of the overall grade), it all counts towards the overall grade.

Explanation / Answer

given final is 20% of the lecture grade, and the lecture grade is 60% of the overall grade

final worth =(20/100)*(60/100) overall grade=(1200/10000) of over all grade=12/100 of overall grade =12% of overall grade

given quizzes are worth 10% of the lecture grade, and the lecture is 60% of the overall grade

so quizzes are (10/100)*(60/100) of overall grade=(600/10000)=6/100 of overall grade =6%overall grade

if each quiz is 2.5%

each quiz worth (2.5/100)*(60/100)=15/10000=1.5% of overall . grade

four quizzes worth 1.5*4=6% of overall grade

so both are same
