The formula for weighted average of grades
Weighted average = (grade1 × weight1 + grade2 × weight2 + ... + gradeN × weightN) / (weight1 + weight2 + ... + weightN). Where grade1, grade2 ... gradeN are the individual grades, weight1, weight2 ... weightN are the corresponding weights, and N is the number of grades and weights.
How to calculate the arithmetic average?
