Ok normally you would find the percentage in doing x/(x+y) * 100

anonymous · Answer

x = grams of salt
y = grams of sugar
x+y = total grams of mixture
percent of salt = x / (x+y)  * 100%

thats exactly finding the substance you want over the total mass that you have 
Ex :
you have 4 grams of sugar, 5 grams of salt you do 
5/9 = 0.56 then multiply by 100 you get 56%
