How do I calculate a final grade with percentages?
MethodFinal Grade = (Grade 1 x 60%) + (Grade 2 x 40%)Short ExamplesQ1. What is the Final Grade if Grade 1 is 95 and Grade 2 is 70?A1: Final Grade = (95 x 60%) + (70 x 40%) = 57 + 28 = 85Q2. What is the Final Grade if Grade 1 is 55 and Grade 2 is 43?A2: Final Grade = (55 x 60%) + (43 x 40%) = 33 + 17.2 = 50.2Long ExamplesQ1. What is the Final Grade if Grade 1 is 95 and Grade 2 is 70?M1: Final Grade = (Grade 1 x 60%) + (Grade 2 x 40%) = (95 x 60%) + (70 x 40%) = (95 x 60/100) + (70 x 40/100) = (5700/100) + (2800/100) = (57) + (28) = 85A1. Final Grade = 85Q2. What is the Final Grade if Grade 1 is 55 and Grade 2 is 43?M2: Final Grade = (Grade 1 x 60%) + (Grade 2 x 40%) = (55 x 60%) + (43 x 40%) = (55 x 60/100) + (43 x 40/100) = (3300/100) + (5020/100) = (33) + (50.2) = 50.2A2. Final Grade = 50.2

How do you calculate the percentage of a test score?
To calculate a test score, you divide 100 by the amount of test questions there are.Once you do that, you get what each question is worth. (DO NOT do this if they are worth different amounts.)You get the number of questions that are wrong and multiply it by the worth of each question. Once you get that answer, you subtract it from 100.For example:Fred takes a 20 question test. He gets three wrong. You do this:100 dvd 20 = 55 x 3 = 15100 - 15 = 85Fred's Score: 85, or B
How do you calculate 10 percent off a product?
To calculate the amount you save if something is 10% off move the decimal one place to the left. A hat that was $20, and is marked 10% off, means you will save $2. The new price woud then be $18,but your question seems to be interested in the amount saved, not the final amount paid.Other examples:$25, means save $2.50$700, means save $70$32.40 means save$3.24and so on

What percent of 80 is 100?
Let x% of 80 be equal to 100.Therefore,(x/100)*80=100x/100=100/80x=(10/*8)*100x=1000/8x=125therefore 125% of 80 is 100.
What's the best way to calculate percentage of something?
Percent just means "per = out of", "cent = [math]100[/math]". Therefore [math]10\% = 10/100 = 1/10 = 0.1[/math] and [math]250\% = 250/100 = 2.5[/math]. Percentages are not limited to [math]100\%[/math] as many children think. A loan shark might charge [math]10\%[/math] per week. That's [math]0.1[/math] times the amount owing and if not paid the amount owing becomes [math]1.1[/math] times the previous amount owing (the previous amount plus [math]0.1[/math] times that). If not paid for a year it would be [math]1.1\times1.1\times\dots\times1.1 = 1.1^{52} = 142.04[/math] times the original amount borrowed, i.e. [math]142.04\times100\% = 14203\%[/math] ([math]\times100\% = \times100/100[/math]). (I subtracted [math]1[/math] because we want the interest not the total including the amount borrowed.) Even a small percentage per week can become thousand of percent per year. For example [math]1\%[/math] per week compounds to [math]1.6777[/math] times = [math]167.77\%[/math], i.e. [math]166.77\%[/math] interest (subtracting [math]1[/math] again).If you just remember that [math]\%[/math] means divided by [math]100[/math] you should have no trouble. So [math]6\%[/math] of [math]20 = 6/100\times20 = 6/5 = 1.2[/math]. And [math]8[/math] is what percentage of [math]40[/math]? Answer: [math]8/40 = 8/40\times100\% = 20\%[/math]. Easy.
What percent of 50 is 20?
In this case, you just double both numbers. 20 out of 50 is the same as 40 out of 100. So 40%.But with more complex numbers I find it’s easiest to use a cross table. If you want to know how much 20 out of 50 is in percentage, you put the main number at the top, the lower number at the bottom, and in the top right you put 100, since you want to know a percentage based on 100.You then solve [math]x[/math] by multiplying the low number times 100 divided by the main number:[math]20 × 100 / 50 = 40[/math]%Alternatively, here is a really handy percentage calculator I often use:Percentage Calculator

If 20,000 is 3.5% of an amount. How do I calculate the original amount?
20,000 is 3.5% of an amount20,000 = 3.5% x AMOUNTFirst of all, we can’t use percentages in a calculation. We need to convert the percentage to its decimal equivalent. To do this, we divide the percentage by 100.3.5% = 3.5/100 = 0.035So our formula becomes20,000 = 0.035 x AMOUNTNext we need to isolate the AMOUNT variable on one side of the equal sign. In this case, we divide both sides of the equation by 0.03520,000/0.035 = (0.035 x AMOUNT/0.035)571,428.57 = AMOUNT (rounded off to two decimal points)
