4. Stan makes his own trail mix for hiking adventures.
The recipe is shown at the right. He realizes he has exactly
1 cup of raisins in his pantry and wants to use the entire
cup in this batch. List the amount of each ingredient Stan
should use to keep the ratios of the recipe equivalent.

Trail Mix Recipe:
1/4 cup of raisins
5/8 cup of chocolate chips
1 1//2 cups of almonds

The quantities specified in a recipe are intended to be proportional. In order to maintain the proportions, all values in the recipe must be multiplied by the same constant.

Stan's pantry holds 1 cup of raisins, which is 4 times the 1/4 cup needed for the recipe. If Stan uses the entire supply of raisins, he can make 4 times the quantity the recipe would normally produce. To maintain the proportions, each quantity in the recipe must be multiplied by 4.

4 × 1/4 cup raisins = 1 cup raisins

4 × 5/8 cup chocolate chips = 5/2 cup = 2 1/2 cups chocolate chips

4 × 1 1/2 cups almonds = 4 +4/2 cups = 6 cups almonds
