A snack mix contains toasted oat cereal, pretzels, and nuts in a ratio of 2:2:1 by mass. What mass of each ingredient is needed to make the following amounts of snack mix? a)330g b)210g c)500g d)750g

Let amounts be 2x , 2x, and x g
I will do the last one, the others are done the same way
d) 2x + 2x + x = 750
5x = 750
x = 150
so we need 300 g of oat cereal, 300g of pretzels and 150 g of nuts. 
2/5 cereal , 2/5 pretzels , 1/5 nuts

If cereal is 2/3, pretzels is 2/5, nuts are 1/5. Ok so you would add them up. 2/3 + 2/5 + 1/5 = well that is your answer. it will not be a answer if their is not a label.
