If the punch recipe is 1/8 frozen juice, 1/8 fruit cocktail etc. then this is to make scaling easier. You'd use equal quantities of all ingredients that are each 1/8, and twice as much of anything that says 1/4
Example: If you wanted to use a whole 12 fl. oz container of juice, you'd need 12fl. oz of fruit cocktail, so you'd have a bit left over. You'd make 8x12=96fl. oz in total . If you wanted to use the whole container of fruit cocktail, you'd need to open a second container of juice. In this sort of recipe though, the difference between 12oz and 15oz is minimal, so you could easily use the whole container of both.
1/8 of 12 oz is 1.5 ounces. 1/8 of 15.25 oz is 1.9 ounces. You can easily look this up on google.
