The ratio of m & m’s to raisins in a bag of trail mix is 3: 5. if there are 36 m & m’s, how many raisins are there?

The correct answer is 60 raisins.  To get this answer you will write a proportion of M & Ms to raisins and create and equivalent ratio using the number 36.  

After you have the proportion set up, you will use cross products to solve for the number of raisins.

You can also use equivalent ratios to find the number of raisins.  

Both of these strategies are shown in the attached picture.
