1 tbsp = 0.5 ounces
the % of root beer in a cola:
we make a a mix if 0.5 ounces root beer and 8 ounces cola. the % of root beer in the cola is
0.5/8.5 = %(1/17)*100
the % of cola in a root beer:
0.5 ounces of the mix above has (8/8.5)*100% of cola and we add it to 7.5 root beer that is 0% cola. the % of cola in the root beer is
(0.5*(8/8.5))/8 = 0.5/8.5 = %(1/17)*100
there is the same amount of root beer in the cola and cola in the root beer.
