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.

just put a thanks and vote for 4 stars, LOL
