Annual interest rate / 12 = monthly interest rate. % Final grade calculator Weighted grade calculation The weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g): Weighted grade = w1 g1 + w2 g2 + w3 g3 +. A scale of 1:100 means that the map distance is 100 times smaller than the real-world distance. C = 2.0. For example out of a sample of 100 children, a percentile value of 40 percent means your child weighs more than 40 children and weighs less than the other 60. Let's move all the other parts of the equation to the other side. So as we have shown before, 0.15 of 250 cookies is thirty-seven and a half.
