Penn buys 3 large sub sandwiches to serve at a party.He cuts the sandwiches into equal pieces and serves 1/4 sandwiches to each guest.
Number of guests g = [tex] \frac{Number of sandwiches(n)}{length of each piece(1/4)} [/tex]
The equation becomes
g= [tex] \frac{n}{\frac{1}{4}} [/tex]
where 'g' is the number of guests and 'n' is the number of sandwiches
Given number of sandwich is 3 so n = 3
g = [tex] \frac{3}{\frac{1}{4}} [/tex] = 3 * [tex] \frac{4}{1} [/tex]= 12 guests
