Answer: 9 cups of cheese crackers will be needed to make 15 cups a snack mix
Explanation:
My famous snack mix recipe calls for 6 cups of cheese crackers for every 4 cups of pretzels.
The ratio of the number of cups of cheese crackers used to number of cups of pretzels used is
Number of cups of cheese crackers / number of cups of pretzels
= 6/4 =3//2
This means that one snack mix cup will require cups of cheese and cups of pretzels in the ratio of 3:2
Total ratio = 3 + 2 = 5
cups of cheese crackers required for 15 snack mix packs will be
Ratio of cups of cheese crackers/total ratio × number of snack mix cups needed
= 3/5 × 15 = 9
