# Math Help - Percentage and marks

1. ## Percentage and marks

If I write 2 maths papers, and I get in:
Paper 1: 90%
Paper 2: 65%

and paper 1 is worth 35% of the total mark, and paper 2 is worth 65%, whats my total?

2. my first answer on this site so dont shhot me down if i am wrong. lets work it out in parts. so the 1st paper is worth 35%. so 35/100 = 1% of the 1st paper. you got 90% so (35/100)*90 is the overall percent of the 1st paper. which is 31.5%
now to do the same thing with the second paper. (65/100)*65=42.25%

therefore your overall percentage is 42.25+31.5=73.75%
(unless ive made a stupid mistake(lack of confidence lol))

3. Also I guess you can verify this method by checking the final marks when you get 100% for both papers, then according to Keaton,

(35/100)*100+(65/100)*100=100%
