Question

If I have 126 lbs of one material and 230 lbs of another material in a product - what are my percentage of each?

Answer 1

The total pounds are 126+230=356. so  to find the percentage of each item of material you would take (126/356)*100=35% and then do the same for the second material (230/356)*100=64.6 or 65%%  if done correctly you can check the math, the two percentages should add up to 100%.   So 35% + 65%= 100%
