Every quiz score is worth 1/20 of a student’s grade at the end of the quarter. Every student will have four quarter grades by the end of the year and each of these quarter grades is worth 2/9 of the student’s Final Year-End grade. The final exam, taken on the last day of school, will be worth 1/9 of the Final Year-End grade. According to this grading policy, the final exam has the same importance (weight) as how many quizzes?

Each quarter is 20 quizzes.
Each quarter is 2/9 of the early grade.

Thus,
Each quarter = 20 quizzes
20 quizzess = 2/9 of yearly grade

If final exam is 1/9 of yearly grade, then how many quizzes is 1/9 of yearly grade equal to?

$\color{#000000 }{ \displaystyle a=b,~b=c,~\therefore~a=c  }$
( $\color{#000000 }{ \displaystyle\therefore  }$ means "therefore" )

you should be able to answer my question...
