Manual weighted grade average formula
Weighted average = (grade1 × weight1 + grade2 × weight2 + ...) / (weight1 + weight2 + ...)
Example substitution into the formula
For example, enter grade 5 with weight 3 and grade 4 with weight 2. Substitute the products into the formula and divide by the sum of weights.
(5 × 3 + 4 × 2) / (3 + 2) = (15 + 8) / 5 = 23 / 5 = 4.6
