Raisins and sunflower seeds are sold together in packages of 250 g. the ratio of the mass of raisins to the mass of sunflower seeds is 3 to 5. determine the mass of raisins in a package. show and explain your work

Mass of the total pack of raisins and sunflower together = 250 gram
Mass of raisins:Mass of sunflower seeds = 3:5
Let us assume the common ratio to be = x
Then
3x + 5x = 250
8x = 250
x = 250/8
   = 31.25
Then
Mass of raisins = 3 * 31.25
                         = 93.75 gram
So the mass of the raisins in the total package is 93.75 grams. I hope the procedure is clear enough for you to understand. Using this method you can always solve similar problems without taking any help from outside. Hope this helps.

There is no question, there is just the answer.
