Question

perl · Answer

it might help to change 7 3/4 to an improper fraction

perl · Answer

7 3/4 
= 7 + 3/4
 = 7/1 + 3/4 
= 28/4  + 3/4 
= 31/4

perl · Answer

now the question says, assuming we are 2/3 of the way , how much time is left for the trip. If you are 2/3 of the way, that leaves you with 1/3 of the way left.
So multiply 1/3  and 31/4
